The festive atmosphere at the Tour de France was interrupted disgracefully overnight when a bottle of urine was sprayed over British champion Mark Cavendish.
It appeared that Cavendish was targeted because of his part in Tuesday's controversial sprint finish in Saint-Malo, when some sprinters blamed him for the clash with Tom Veelers in which the Dutchman suffered a heavy fall.
Cavindish had an upbeat attitude about his shower, tweeting "The apple juice looks far from appetising for me tonight... And I'm not taking the p---. Did that once already today."
But the flying urine definitely came as a shock, and it was certainly not the yellow jersey he would have dreamed about before the race.
Here are six other examples of novelty objects thrown at sports events.
Car door - 2002 Football Kingz
When Chile played the Football Kingz in a World Cup warmup match in 2002, a supporter ran onto the pitch in the 80th minute carrying a car door.
The presence of a few hundred New Zealand-resident Chileans excitedly massing by the touchline had prompted the announcer to ask fans not to invade the pitch at the end of the game. After the car-door incident he had to follow this up with a request for fans 'not to bring car parts on to the pitch'."
Flour-bomb - 1981 All Blacks test
The 1981 Springbok tour of New Zealand is remembered most for the political turmoil off the field, culminating in a light airplane circling the pitch during the final match in Auckland, and dropping flour bombs.
Security at the ground was tight, so the battle was taken to the sky as Marx Jones and Grant Cole hired a Cessna aeroplane, and circled the stadium for the duration of the match. They dropped flares and flour bombs in an effort to stop the game.
The match continued, and it was ironically All Black prop Gary Knight who was felled by a flour bomb. Marx Jones spent 6 months in prison following the events of that fateful day.
Octopi on Ice - Detroit Red Wings
For nearly 50 years, hockey fans in Detroit have been throwing octopi on to the ice after a big win by the Red Wings.
The tradition started in 1952 during the Red Wings' Stanley Cup run. Two brothers, who owned a fish shop in Detroit threw an octopus on the ice during a game in Detroit.
Each tentacle of the octopus was symbolic of a win in the playoffs. The largest octopus to be thrown on the ice was a 50 pounder in 1996. The creature was proundly displayed on the hood of the Zamboni while the ice at the Joe Louis Arena was being cleaned between periods.
Bullet - Julian Dean on Tour de France
Tour de France riders Oscar Freire of Spain and New Zealand's Julian Dean were shot at with air guns during the stage from Vittel to Colmar in 2009.
The bullets - which were thrown from the bb gun - hit Freire on the leg and Dean on the hand, but the Kiwi brushed off the attack saying he was surprised something like this hadn't happened before.
"But it's okay, it's not a drama. It's nothing really, it didn't bother me at all. Compared to the crashes we have it was actually pretty light really," he said.
Beach ball - Liverpool 2009
Some Liverpool fans claim a beach ball robbed their side of any chance to win the English Premier League title in 2009.
Five minutes into their game with Sunderland at the Stadium of Light, a child threw a large Liverpool beach ball onto the field.
No one did anything about it. Sunderland's Darren Bent fired a shot that struck the beach ball and was deflected wide of Liverpool goalkeeper Pepe Reina.
The goal was allowed, despite valid Liverpool protests that the referee should have stopped play, and Sunderland went on to win, 1-0.
Coin - Rio Ferdinand 2012
Rio Ferdinand was struck by a coin from the crowd as he celebrated Manchester United's derby victory at the Etihad Stadium in 2012.
The former England captain then confronted a Manchester City fan who ran on the pitch towards him in an ugly end to proceedings.
After the match, Ferdiand tweeted: "what a result,3points! Sweet! Whoever threw that coin,what a shot! Can't believe it was a copper 2p....could have at least been a £1 coin!"
