I got handcuffed to a bed at a police/fireman's party back when I was about 20. I was in the wrong place at the wrong time ... drunk cops. My GF at the time was living with the police dispatcher who had the party.

It worked out and I got laid while I was waiting. About 4 hours later someone finally got a key and let me go. Thank god I wasn't drinking that night cause if I had to take a piss I'd have been f'd. I left that party soon as I got let loose -- before they got any drunker and came up with something else to do.
