comment: I think farts are hilarious and they make me laugh whenever I hear one. 
  But I totally agree, I would never fart around others and expect them to laugh. The sounds funny but to try and get people to smell them is just gross and I totally understand people who are squeamish about it.
  If it's an accident then I wouldn't judge someone for it (I'd just keep a distance for the odor) but to do it deliberately isn't nice.
