My friend came up with a drinking game: every player in turn has to get up and flirt with someone/thing in the room using a really lame pick up line. If they get a number, they win, and everybody drinks. If they don't, they lose, and they drink.
We played to lose.
I drew some of our more interesting methods. In retrospect, they weren't really comic worthy, but by god I drew them and you will appreciate them!!
I cannot stress this enough: being weird to strangers is fun
