Once a blonde kept having the same weird dream every day, so she went to her doctor.
Doctor: What was your dream about?
Blonde: I was being chased by a vampire!
Doctor: Really… What was the scenery like?
Blonde: I was running in a hallway.
Doctor: Then what happened?
Blonde: Well, that’s the weird thing. In every single dream, the same thing happened. I would always come to this door, but I couldn’t open it. I kept pushing the door and pushing the door, but it wouldn’t budge!
Doctor: Did the door have any letters on it?
Blonde: Yes, it did.
Doctor: And what did the letters spell?
Blonde: It said, “P-U-L-L.”
