Bubba went to Texas A & M on a football scholarship. He was a great running back, but a poor student.
Come graduation day, Bubba didn't have enough credits. But he was a great football star and the students held a rally and demanded the dean give him a diploma anyway. They were so insistent that the dean agreed if Bubba could answer one question correctly he would give him a diploma.
The one question test was held in the auditorium and all the students packed the place. It was standing room only.
The dean was on the stage and told Bubba to come up. The dean had the diploma in his hand and said, "Bubba, if you can answer this question correctly I'll give you your diploma."
Bubba said he was ready and the dean asked him the question. "Bubba," he said, "How much is three times seven?"
Bubba looked up at the ceiling and the down at his shoes, just pondering the question.
The students yelled "Graduate him anyway! Graduate him anyway!"
Then Bubba held up his hand and the auditorium became silent. Bubba said, "I think I know the answer. Three times seven is twenty-one."
A hush fell over the auditorium and the students began another chant.
"Give him another chance! Give him another chance!"
