Two Texas A&M University Aggie football players were taking an important exam. If they failed, they would be on academic probation and not allowed to play in next week's big game

The exam was fill-in-the-blank. The last question read, "Old MacDonald had a _____."

Well, Bubba was stumped. He had no idea what the answer might be. He knew he needed to get this one right to be sure he passed. He looked around to make the professor wasn't watching, then 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 and said, "Bubba, you're so stupid. Everyone knows that Old MacDonald had a farm..."

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

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