This guy goes to see his doctor and tells him, “Every time I fart, it sounds like a Honda motorbike.
The doctor tells the guy to pull down his pants and bend over. As he does so, the guy farts and sure enough, it sounds just like a Honda motorbike.
The doctor immediately says to the guy, “I know the problem – you’ve got an abscess up your arse.”
The guy says: “What?! Surely an abscess can’t make my farts sound like that?”
The doctor says: “Didn’t you know? Abscess makes the fart go Honda!”
