A buddy of mine works for a company that produced Saint's Row III and they had a release party a few days ago. Since I have nothing going on, he got me into the party as his "plus one." Yes, that elicited a lot of gay jokes, but I'll put up with a lot for a night of free food and booze.
Also, nerd parties are hilarious. Throw a bunch of socially inept people into a bar with free alcohol and you've got yourself an entertaining night.
