In this day and age (the information age), it is a disgrace that there are so many people unschooled in farting etiquette. This is an intolerable situation (no wonder the U.F.O.'s won't stay here), besides, there is enough global warming. I'm serious, years ago, there was an international study on the causes of global warming. The major cause was found to be COW FLATULENCE, so let's not add to the problem (and believe me, we humans can really do some damage). Maybe we can discover the proper "farting chemistry" so we can be more environmentally friendly.
