Reminds me of a story my grandfather once told me:
At a very official dinner, there was this young lady sitting between a well-dressed gentleman and a bum (how the bum got invited is something I've never figured out).
At some point during the meal, the young lady built up gas
. She tried to keep it in
, but at some point the pressure was too much and she let out a loud, smelly one.
FRRRRRRRRRRRRRRRRAP! 
The gentleman then gets up and takes the blame on himself: "Respected Ladies, dear Sirs, I apologize and am deeply ashamed for this mishap, I have been having digestive problems, and I hope that you will forgive me and that we can forget this unpleasant occurrence. Please don't let it ruin your evening." 
As the gentleman sat down, the young lady sent him a grateful glance and resumed her meal. A little later, the lady felt another one building up, but felt a little more confident than previously, and thus didn't make a serious effort to keep it in. And so she ripped another loud one, and acted innocent 
This time the bum gets up and adresses the gathering: "Ladies and gentleman, I don't know nice words as the gentleman there, but this time the lady's fart you can blame it on me."

At least there was a good intention behind it
