lol, that happened to my buddy (more or less). He went to a party with me, got drunk there, walked back to his house, got a bottle of vodka, went back to the party, got even drunker, brought a girl home, but couldn't get his key in the door! He ended up dropping the key (under his porch), taking a photo of the door, and sleeping in his car, and remembering barely any of it. He doesn't even remember what the girl looks like or what her name was.
