Whether you call it gas, flatulence, or hot air, there is one thing that is always true: FARTS STINK! Although occasionally you may encounter someone who is actually proud of their farts, most people are embarrassed when the involuntarily pass gas. In fact, often people will even pretend that it was someone else who emitted the noxious fumes by asking, "Who farted?" when it was actually they who farted. Such deceitful behavior cannot be tolerated and it is for this reason that Fart Goggles have been invented. Indeed, they will allow you to be able to "know who to trust and know who lies" as stated in the song. They come with a camera which will record the evidence and hold those who have offended your sense of smell (and decency) accountable for their rude and unacceptable behavior. But, be forewarned, others will also be armed with Fart Goggles and will vigilantly be attempting to record your farts too. Hopefully the result of all this fart-watching will be a world free of offensive odors!
