- Sock on the door (Things)
"I didn't see the sock, so I figured there was nothing nasty going down."
What to do, what to do? The date looks like it's going to end well, but your roommate is going to be home any minute. If only there was a signal you could use to let him know that you're gettin' some girlie action, so he can go find somewhere else to crash for the night. Well, you've got a few options. Hang a sock or a tie on the door, shove a chair under the doorknob, and lock your roommate out, or you can just hang a big sign on the door saying, "WOOHOO!!!" Meryl's boyfriend Sully and his roommate Glen apparently go for the more subtle, less exciting, sock on the doorknob.
