Whats the most embarrassing thing you have done on a dare or a lost bet?

[c=#7700B2]nude run around friends huge ass backyard during a party of hers .. luckily I was really intoxicated and don't remember it but being told about it was embarrassing enough for me that I just wanted to dig a hole in ground and bury my head in it like a emu or whatever big bird does that[/c]
