"Tough Final"

Two football players were taking an important final
exam. If they failed, they would be on academic
probation and not allowed to play in the Sugar Bowl
the following week. The exam was fill-in-the-blank.
The last question read, "Old MacDonald had
a _________."

Bubba was stumped. He had no idea of the answer.
He knew he needed to get this one right to be sure
he passed. Making sure the professor wasn't watching,
he tapped Tiny on the shoulder.

"Pssst. Tiny. What's the answer to the last question?"

Tiny laughed. He looked around to make sure the
professor hadn't noticed then he turned to Bubba.

"Bubba, you're so stupid. Everyone knows Old MacDonald
had a farm."

"Oh yeah," said Bubba. "I remember now." He picked up
his No. 2 pencil and started to write the answer in the
blank. He stopped. Reaching to tap Tiny's shoulder again,
he whispered, "Tiny, how do you spell farm?"

"You are really dumb, Bubba. That's so easy. Farm is
spelled - E-I-E-I-O."
