Tommy is a young boy, just potty trained. When he goes to the bathroom though, Tommy manages to hit everything but the toilet. So, his mom has to go in and clean up after him.
After two weeks, she has had enough, and takes Tommy to see the doctor.
After the examination, the doctor said, “His unit is too small. An old wives’ tale is to give him two slices of toast each morning, and his unit will grow so he can hold it and aim straight.”
The next morning Tommy jumped out of bed and ran downstairs to the kitchen. There on the table, are twelve slices of toast.
“Mom!” Tommy yells. “The doctor said I only had to eat two slices of toast.”
“I know,” said his mother. “The other ten are for your father.”
