I once ordered a pre-pay £100 luxury taxi from my mates house to London....I stood across the road and watched his mum go psycho at the driver Another good thing to do is to sellotape things all over people when they've passed out at a party. A mate of mine sleeps like a BRICK when hes drunk, so we managed to sellotape guitar practice amps, books, bottles, clothes, sheets of paper and pens all over him, that was funny as f**k!
