Can anyone give me some ideas for games to be played by the adults at a 30th birthday party....Please help!

I am working on a 25th b'day party. I am shooting for an island theme. If you get any hits please let me know I will do the same!

AHHH! Time is running out! The party is Saturday and we haven't a clue what the adults can play. We wanted to do something that would be somewhat making fun of the birthday person. Oh and I'll let you know if I get any ideas for your island theme party.
