Little Johnny's parents were trying to potty train him. When he went to the bathroom, though, he hit everything but the toilet. Mom would then have to go in and clean up after him.
After two weeks, she had had enough, and took Johnny to the doctor. After the examination, the doctor said, "Well, his unit is too small. An old wives' tale says to give him two slices of toast each morning and his unit will grow. He will then be able to hold it and aim straight."
Next morning, Johnny jumped out of bed and ran down to the kitchen. On the table were 12 slices of toast.
"Mom," Johnny yelled, "the doc said I only had to eat 2 slices!"
"I know," his mom said and smiled. "The other 10 are for your father."
