For the bored

It only works in real life I'm afraid. You also need iTunes and a big enough music library to make it work. It goes like this:

The chooser-person types some random word into itunes search box. Preferably something silly like 'tits'

then they play the resulting playlist of songs which include this word in their titles/artist names

First person to guess the word (just from listening to the playlist) wins. every incorrect guess and they have to down a shot or something
