WATCH: Cyclist Mark Cavendish rips into a journalist over doping question

Mark Cavendish clearly doesn't take stupid questions very well.

During a press conference for the Tour de San Luis in Argentina, the British cyclist was asked if he could be 100 per cent sure that his fellow professional riders were drug free.

He pulled no punches with a devastating response.

"Can you tell me 100 per cent that one of these journalists isn’t ******* your wife?

Cavendish continued: "Where there's money to be gained, there'll be the odd ******** who cheats but cycling is miles ahead of other sports when it comes to testing.

"I hope everyone's correct but with human nature, you can never be certain. But the positive that I can take is that if someone is cheating, he will be caught."

File that one under "Ouch".
