Athletes look to gain whatever edge on their opponent that they can, even if it's foul.

A match at the Grand Slam of Darts in England ended in controversy last week when a "he who smelt it, dealt it" argument was stirred up.

47-year-old Gary Anderson, who's a two-time world champion, beat a 34-year-old Wesley Harms. Afterwards, Wesley blamed it on Gary distracting him by passing nasty silent gas."It'll take me two nights to lose this smell from my nose," Wesley said.

Gary is fighting back hard. "If the boy thinks I've farted he's 1,010% wrong. I swear on my children's lives that it was not my fault." In fact, he thinks it was WESLEY who was passing the gas. "Every time I walked past [him] there was a waft of rotten eggs."

I guess we'll never know who dealt it. Since passing gas during a darts match isn't against the rules, odds are there's not going to be much of an investigation.
