Once a Safety Officer kept having the same weird dream every night, so he went to a doctor.
Doctor: What was your dream about?
Safety Officer: I was being chased by the fire warden!
Doctor: So... what area are you in?
Safety Officer: I was running in a hall way.
Doctor: Then what happened?
Safety Officer: Well that's the strange thing. In every single dream, the same thing happened. I always come to this door, but I can't open it. I keep pulling the door and pulling the door, but it wouldn't budge!
Doctor: Does the door have any letters on it?
Safety Officer: Yes it did.
Doctor: And what did these letters spell?
Safety Officer: It said "Push"
