"What happened?" asked the hospital visitor of the heavily bandaged man sitting up in bed.

"Well, I went down to the amusement park over the weekend and decided to take a ride on the roller coaster.  As we came up to the top of the very highest loop, I noticed a little sign by the side of the track.  I tried to read it but it was very small and I couldn't make it out.  I was so curious that I decided to go round again, but we went by so quickly that I couldn't see what the sign said.

By now, I was determined to read that sign so I went round a third time.  As we reached the top, I stood up in the car to get a better view."

"And did you manage to see what the sign said this time?" asked the visitor.


"What did it say?"

"Don't stand up in the car!"
