Water for hole

A man driving a motor-home got hopelessly bogged down in an unexpected muddy hole along a dirt road. After a few minutes, a passing farmer drove by on his tractor and offered to pull him out for only $25.

After the motor-home was back on dry ground the man said to the farmer, "At those prices, I bet you're pulling vehicles out of this mud day and night."

"Can't," replied the farmer. "At night I haul water for the hole."
