Once Khan Lala kept having the same weird dream everynight, so he went to a doctor.

Doctor: What was your dream about?

Khan Lala: I was being chased by a vampire!

Doctor: (giggles quitely) So... what is the scenery like?

Khan Lala: I was running in a hall way.

Doctor: Then what happened?

Khan Lala: Well that's the weird thing. In every single dream, the same thing happened. I always come to this door, but I can't open it. I keep pushing the door and pushing the door, but it wouldn't budge!

Doctor: Does the door have any letters on it?

Khan Lala: Yes it did.

Doctor: And what did these letter spell?

Khan Lala: It said "Pull"
