Halloween parties are a great opportunity for random hook-ups. Especially because every girl is wearing a sexy costume. We don't know that for fact, since we haven't been invited to a Halloween party in years. We based that info on the comments people with lives make on their Facebook pages.

The costume party nookie potential is one of the reasons this video from comedian Aaron Karo is so funny. A Halloween hook-up can end with a sleepover at a sexy stranger's house. That's always fun.

The next day, well, it's not so much fun anymore.

[WARNING -- Video is NSFW-ish for a naughty word at the end.]
