One day a blonde, brunette, and redhead were on top of a burning building. When the firemen got there they stretched the trampoline out and told the brunette to jump. She jumped, then the firemen moved back and she died.
Then they moved back and told the redhead to jump. She said ''No! I saw what you just did!'' The firemen replied, ''we don't like brunettes, we won't move this time!'' So she believed them and jumped. They moved again, then returned to where they were.
Then they told the blonde to jump. She replied ''No I saw what you did to them!'' The firemen said, ''we don't like brunettes or redheads, we like blondes!'' She then said ''OK! I'll tell you what to do! All of you put the net on the ground and BACK UP!''
