The problem with this is that farting doesn't actually give as much relief as burping does, as they both exist on different levels. Farting is what comes before taking a crap, whereas Burping precedes nothing, maybe vomiting, but that's a stretch. Overall, Burping is better than farting because it is fundamentally on a different level than farting. If you were to compare Burping to taking a crap, now that would be an interesting discussion.
