There was a South Park episode not long ago where there was no more internet, and Kyle's father was having withdrawals from his daily dose of Brazilian Fart Porn.
So. You guessed it. Today I googled Brazilian Fart Porn. What? Aren't you the least bit curious to know if it really exists? I will let you solve that little mystery on your own, but in my quest for the South American flatulence fetish, I came across quite possibly the funniest thing I have ever seen on video in my life: Tourettes Guy. I CRIED from laughing so hard, and then promptly watched the thing again and laughed even harder. I would love to have this man over for some wine and cheese.
Obviously, don't watch if you are offended by coarse language.
