It was graduation day, and everybody's going to get their diploma but David.
At the assembly, the entire senior class stands up and shouts "Let Dave graduate, let Dave graduate!"
The principal agrees to give David one last chance.
"If I have five apples in my right hand and five in my left hand, David, how many apples do I have?" he asked.
Dave thought long and hard and then said: "Ten."
At that the entire senior class stood up and shouted, "Give Dave another chance. Give Dave another chance!"
