April Fools' Day only comes around only once a year, so this is the only chance companies can prank the rest of the world. Here is a list of the best pranks of 2017 so far.

Virgin Australia: Dog flight attendants

Virgin Australia decided to prank those on Facebook with an ad showing off its new "canine flight crew members". Along with a very cute video of these dogs, Virgin Australia posted the following comment:

"Today we are excited to unleash our new Virgin Australia Canine Crew in a world first initiative. On select flights, a Canine Crew member will work alongside our award-winning Cabin Crew team to offer a range of additional services.

"Congratulations to all pooches who have completed their rigorous training program and officially take to the skies for the first time today."

Honda car emojis

Honda followed suit with an advertising prank. The car manufacturer has put out a commercial advertising a horn that helps you express your feelings while driving. The horn features emoji buttons that make corresponding horn sounds. So while you're cruising along, you can let the driver next know if you're happy - or possibly upset with their driving.

Zipline for One Tree Hill

. If you thought a half-price deal to zipline 800m off the peak of One Tree Hill was too good to be true - well, you were right.

The wild ride would apparently let tourists and thrill-seekers whizz down the side of Maungakiekie at barely-believable speeds of more than 190km/h, passing over Cornwall Park before coming to rest in a paddock, 800m from the volcano's summit.

By midday today more than 3000 had clicked on the web link and more than 300 people had attempted to purchase the deal.

Brendon McCullum jockey apprenticeship

The TAB Trackside decided to pull a prank on their Facebook by sharing an "exclusive video" of cricketing legend Brendon McCullum announcing he will begin his jockey apprenticeship in the new season.

During the video he explains how he has been "thinking about it for awhile and the time is right." When asked, "What are you doing this make this happen?" McCullum hilariously responds with, "The first thing I had to do was give up Speights, which was pretty tough."

The prank didn't seem to fool many, but got at least 73 shares, 425 reactions and 289 comments.

NZ police bunnies

Waikato District Police also shared a prank on Facebook announcing their new crime fighting units - bunnies! The post explains they are "specially trained to sniff out stolen jewellery during search warrants." Apparently the operation is going well and "they really have a nose for it."

I know we have mentioned this initiative previously when it was under development; but: Police have a new crime fighting...

Burger King Whopper toothpaste

On Wednesday, the fast food chain announced the launch of the "Whopper Toothpaste" that is said to keep your mouth "Whopper fresh" all day long.

The toothpaste claims to contain "active Whopper extracts" and embody "the iconic flavour of the Whopper and combine it with active ingredients for optimal teeth and gum hygiene", the company stated in a press release.

Complete with full 60-second ad, Burger King has not let us down with its deadly serious movie-like trailer boasting "you won't have to hesitate between enjoying a Whopper and brushing your teeth ever again".

Google

Pac man:

Google tends to do a lot of April Fools pranks every year. One included turning Google Maps into a functional Pac Man game. It's pretty entertaining being able to able play a classic arcade game in your own street.

Google Gnome:

This new device is quoted "the next evolution" from Google home. Apparently, Google Gnome is a voice-activated, hands free tools that gives you information about your back yard. A fake advertisement shows people asking the Gnome several questions from "How's the weather?" to "Can I eat this daisy?". Google Gnome can even turn your hose on and off. I think a lot of gardeners would be happy if this device really existed.

SodaStream- NanoDrop

Sodastream went the extra mile with this prank, involving Paris Hilton. This fake commercial advertises NanoDrop, "a cutting edge, state of the art condensed from of sparkling water". In other words, having one drop of this water will quench your thirst, meaning we can save planet earth by using less plastic. Paris Hilton's delivery of this advertisement is quite serious, which makes this fake ad even more hilarious.

KFC Bucket

In Canada, the fast food chain released a fake ad for a voice-activated smart device - shaped like a KFC bucket. Even though the ad doesn't say much, the futuristic vibe makes the "product" very interesting. What would the device do? Order us KFC? It's a mystery.

Duolingo Emoji Course

The language learning site has made a unique course for April Fools, teaching users the language of Emoji. This "course" comes with a flash card set to help you learn. Too bad this isn't real, this would actually be useful for adults to figure out what their teenagers are messaging each other.

Deliveroo goes sky high

Today, Deliveroo launched its Extreme Delivery service that engages skydivers rather than bike riders to deliver food to a broader location base. Deliveroo partnered with Melbourne-based phenomenon, Huxtaburger, delivering its mouth-watering burgers to locations off the beaten track.

The tattoo spell checker app

Travel Insurance Direct launched a new app, known as the 'TID: We've Got Your Back' App, a free tattoo spell checker. Ahead of tourists getting inked, the App will simply scans the artist's flash-sheet to reveal any pesky tattoo typos among English, Thai and Indonesian characters, ensuring they aren't scarred for life.
