A company of firefighters had come on duty after a night on the town and were quite inebriated. A half hour went by and they got a call and the alarm went off. They drove to the scene where a brunette, a red head and blonde were trapped on the roof.
As it turned out they forgot the ladder so they had to use the net. The brunette jumped, but the men were still gassed and they lowerd the net. The poor brunette hit with a thump in the grass but was only bruised.
The red head decided she wasn't going to jump but the firefighters begged her to saying that red was their favorite color. Seeing the flames getting closer she jumped, with the same result.
By this time the guys were starting to sober up and genuinely begged the blonde to jump, but she wouldn't. She said "I saw what you did to the brunette and the red head! No way I'm gonna be fooled. If you're serious about me jumping you'll put the net down on the sidewalk and back away from it." So they did.
