The Contest

Eventually the matter boiled down to Thompson and Brown, and the scholarship of each one boiled up so that both were held even for half an hour.

Finally Thompson said, "How does a gopher dig a hole without leaving a mound of sand at the lip?"

Brown thought about that and said, "I can't answer that. However, since it's your question, you had better answer it."

Thompson said coolly, as he reached for the accumulated pile of bills. "Easy. The gopher starts at the bottom of the hole and that's where he leaves the sand."

"Hold on," said Brown heatedly, grasping Thompson's wrist to prevent him from taking the pot. "How does the gopher get to the bottom of the hole in the first place?"
