3 friends all wanted to go to the same college ...

One of them said," I.U."
The next guy said," Let's go to Notre Dame."
The last guy said," Let's go to Purdue."
To decide between themselves they all decided to give reasons.
The I.U. guy went first. He said," At I.U. they teach you good education skills."
The Notre Dame guy was next. He said," At Notre Dame they teach you great athletic skills."
Finally it was the Purdue guy's turn. He said," We really need to go to Purdue, because there they teach you to tell the truth."
