Fire in Pittsburgh
There were 3 football fans, one each from Baltimore, Cincinnati, and Cleveland, standing on a burning roof in Pittsburgh. The fire department came with a blanket and yelled to the Cleveland fan to jump. He jumped and they moved it to the right. He hit the sidewalk with a splat.
They then called to the Baltimore fan to jump. He said that he wouldn't jump. The Fire fighters said they liked The Ravens more than the Browns. So the fan jumped and the fire department moved the blanket to the left. The Cleveland fan hit with a splat on the sidewalk.
Then they called to the Cincinnati fan to jump. He said that he wouldn't jump. The fire department said they hated the Ravens and the Browns, but it would be safe for him to jump. He yelled back, "No way, I'm too smart to fall for that, lay the blanket down on the sidewalk, and then I'll jump!"
