I did once. My friend and myself decided to call another friend whilst we were absolutely hammered and sing "Superwoman" by Karyn White. He was laughing so hard listening on his phone at a club that the bouncers wanted to know what was wrong with him. I don't do this regularly, but my cousin does during all hours of the night and believe me its hilarious. From him moaning about loosing $20 to a game of poker and giving his friend the same amount and that friend winning $400 and saying "Hello" to the nice white guy named Bob. His antics in a club paying $10 for a girl's drink she walked away he called her a B**ch, I asked him then where she was and he said "Right next to me".
