"The Simpsons are going to..." So starts at least one episode of each season. The family have visited every continent during their 30 years on the air (Lisa, Marge, Maggie, Homer and Bart first appeared on April 19, 1987, as a cartoon short The Tracey Ullman Show) - including Antarctica - providing no shortage of national stereotypes.
Here are 10 of the best episodes that feature an overseas trip, along with some the funniest quotes.
One of the earliest and most memorable of the family's holidays. Bart calls at an Australian household (claiming to be from the "International Drainage Commission") to find out which direction the water flows down their lavatory. The subsequent AUS$900 phone bill, and Bart's taunting, spark a diplomatic incident. The Simpsons get a free trip to Australia where Bart is threatened with a "booting".
Homer: Look at this country: U-R-Gay!
Marge: I'll just have a cup of coffee.
Bartender: Beer it is.
Australian man: You call that a knife? This is a knife!
Bart: That's not a knife. That's a spoon.
Australian man: Alright, alright, you win. Heh. I see you've played knifey-spooney before.
Bart: Mom, Dad, just so you don't hear any wild rumours, I'm being indicted for fraud in Australia.
Homer: That's no reason to block the TV.
Homer: What kind of a sick country would kick someone with a giant boot?
Evan Conover: Mr. Simpson, shush! Disparaging the boot is a bootable offense. It's one of their proudest traditions.
While it featured briefly in 'Bart-Mangled Banner' and 'The Devil Wears Nada' (when Carl flirts with Carla Bruni), France gets the full treatment in a first-season episode, 'The Crepes of Wrath'. Bart is sent there on a student exchange trip where he is forced to run errands for a evil pair of winemakers who load their booze with antifreeze. But Bart foils their plan, miraculously learning French in the process.
Principal Skinner: Mr. and Mrs. Simpson, we have transcended incorrigible. I don't think suspension or expulsion is going to do it. I think it behooves us all to consider... deportation.
Marge: Deportation? You mean kick Bart out of the country?
Homer: Hear him out, Marge.
Bart: Ah, the life of a frog. That's the life for me.
Marge: Homer, I'd love a glass of that wine Bart brought us.
Homer: [grunting] Sorry, Marge. Some wiseguy stuck a cork in the bottle.
There's a meeting with Mr Sparkle in Season 8, but it isn't until Season 10 that the Simpsons set foot in the Land of the Rising Sun. They attend a sumo wrestling tournament, get a job at a fish-gutting factory in Osaka, and end up on a TV game show (with the snappy title 'The Happy Smile Super Challenge Family Wish Show'), while Homer learns origami.
Bart: Knife goes in, guts come out.
Homer: If I wanted to see Japanese people, I could have gone to the zoo!
Homer: What? The man who washes the elephants is Japanese! His name is Takashi. He's in my book club!
Wink: Mr. Simpson, we'll cut you down as soon as you answer one question about Japan.
Homer: Is the answer Japan?
Wink: ...actually, it is.
Tanzania (and elsewhere in Africa)
Bart got an elephant (Stampy) in series five, but the family see them in the wild in series 12 after they win a holiday. They fly to Tanzania, before embarking on a whistlestop tour of the continent, visiting Victoria Falls, Ngorongoro Crater, Olduvai Gorge, and Mount Kilimanjaro, and meeting a group of Maasai tribesmen. They eventually visit a chimpanzee sanctuary, complete with a parody of Jane Goodall.
Kitenge: Good night. Don't let the bed bugs paralyse. [leaves]
Marge Simpson: Homer, did you remember to tip Kitenge?
Kitenge: [from outside the door] No, he did not.
Flight Attendant: Attention Passengers - Please prepare for our landing in Tanzania.
(Someone hands her a note)
Flight Attendant: I'm sorry. It is now called New Zanzibar.
(Someone hands her another note)
Flight Attendant: Excuse me. It is now called Pepsi Presents New Zanzibar.
The Simpsons visit London in season 16, where they rent a Mini Cooper and visit the sights, before Homer ends up in the Tower of London for claiming the Queen is an imposter named "Henrietta R. Hippo". Tony Blair, who Homer mistakes for Mr Bean, J.K. Rowling and Ian McKellen all feature as themselves.
Homer: Marge I'll be on my best behaviour. You have my word as a gentlemen and a lady. Now let's see, which rifle should I bring?
Homer: We're big shot tourists from everyone's favourite country, the USA. We saved your ass in Vietnam and shared our prostitutes with Hugh Grant, so give me some free maps and none of that dry British wit.
Homer: Well Marge, you gotta admit, I've been on my best behaviour this trip.
Marge: You punched out three people on the street.
Homer: That was over soccer results. Can you believe they gave Giggs a yellow card in the box?!
Homer does the unthinkable in season 16, and pretends to be Selma's husband to help her adopt a child from China. The whole family joins them on the trip, which includes a visit to Tiananmen Square, where a sign reads: "On this spot in 1989, nothing happened."
Bart: What the hell's menopause?
Homer: Son, menopause is when the stork that brings babies gets shot by drunken hunters.
Madam Wu: Lisa, soon you will have a Chinese baby sister who will surpass you academically.
Lisa: I don't know about that. I'm considered pretty smart.
Madam Wu: Well, Tibet was considered pretty independent. How'd that work out?
The Simpsons join the Flanders for a trip to Jerusalem in season 21. Sights including the Wailing Wall, the Dome of the Rock, the Church of the Holy Sepulchre and the Dead Sea appear, while Sacha Baron Cohen guest stars.
Ned Flanders: Homer, our Bible study group is going to the Holy Land. I would like to invite you and your family to come as my guests.
Homer: Let's see: go to a war zone with a busload of religious lame-os, in a country with no pork and a desert with no casinos. Where do I sign up?
Homer: It's so cool here in the Tomb of the Unknown Savior.
Ned Flanders: Unknown? He's the most famous person who ever lived!
Homer: Porky Pig?
Ned Flanders: Porky Pig isn't a person! He's a pig, and he's not even a real pig!
Homer: But he is buried here, right?
Lisa sponsors a South American orphan (named "Ronaldo") in season 13, racking up a huge phone bill in the process. The family head to Brazil to find him, where Homer is kidnapped and Bart is eaten by an anaconda.
Bart: We'll never find Ronaldo.
Woman: (Gasps) Ronaldo?
Homer: Do you know him?
Woman: No no. I was just distracting you while my children rob you.
Homer: Can we stop? I have to go to the bathroom.
Kidnapper: You just went five minutes ago!
Homer: I have a bladder the size of a brazil nut!
Kidnapper: We just call them nuts here
The Simpsons visit Ireland in season 20. Homer and Grampa spend most of the episode boozing, before buying a pub called O'Flanagan's, while Marge, Lisa and Bart embark on a geographically improbable tour of the country, visiting Dublin, Blarney Castle and Giant's Causeway.
Lisa: Ireland is the leader in communication technologies in all of Europe.
Bart: Take that, Belgium!
Bart: A house and garden show?
(Bart, Lisa and Homer groan)
Bart: You told me we were going to a video game expo!
Lisa: You told me we were going to clean trash on the freeway!
Homer: You told me something but I wasn't listening!
Mr Burns instructs Homer to head to Italy in season 17, in order to pick up a recently purchased "Lamborgotti Fasterossa". The rest of the family tag along and they all visit a Tuscan village called "Salsiccia" and Rome - where they see Trajan's Column and the Colosseum.
Homer: Why can't you people learn to speak my language? I learned to eat your food!
Homer: You're sending me to Italy?
Mr. Burns: Yes.
Homer: Can I take my family?
Mr. Burns: Sure.
Homer: Do I have to hang out with them?
Mr. Burns: It would be nice.
Best of the rest
Homer and Mr Burns visit Cuba in 'The Trouble with Trillions'. Best gag - Mr. Burns: "Sorry about the landing, boys. This fog is so thick, I can't see my own cataracts."
It's not exactly a holiday, but in season 10, Homer joins Mr Burns, Groundskeeper Willie and Professor Frink on a trip to Scotland to capture the Loch Ness Monster. Best gag - Marge: "When was the last time we went for a good old-fashioned family walk?" Homer: "Well, we stopped those when the kids said I was too fat to carry".
"Why can't you people learn to speak my language? I learned to eat your food!" - Homer Simpson
'Lost Verizon' features a trip to Machu Picchu. Best gag - Bart: "Viagra... 5 dollars a pill?
Whatever it is, it's going into Skinner's coffee."
