There were 3 basketball players, one each from IU, Notre Dame, and Purdue, standing on a burning roof in Indianapolis. The fire department came with a blanket and yelled to the Notre Dame player to jump. He jumped and they moved it to the right. He hit the sidewalk with a splat.

They then called to the IU player to jump. He said that he wouldn't jump. They said they liked IU better than Norte Dame. So he jumped and the fire department moved the blanket to the left. The IU player hit with a splat on the sidewalk.

Then they called to the Purdue player to jump. He said that he wouldn't jump. The fire department said they hated IU and Notre Dame. He yelled back, "Lay the blanket down on the sidewalk, and then I'll jump!"
