I just stumbled across this vid about a guy by the name of Sarge, it is damn funny, so much so I was laughing my f-ing ass off watching it.
Hope you'll enjoy too.
In this vid he is giving his sage advice on how to do two chicks at once. Or how to engage in a threesome. lol

I think watchin this will increase your vocab like tenfold as the delivery is outstanding. Nothing like they teach you at school, where they deliberately bore you to death with crappy dialogues.
