"HELP IT GROW" joke

Little Johnny was a young boy, just potty trained. When he went
to the bathroom though, he hit everything but the toilet.
So mom had to go in and clean up after him.
After two weeks, she has had enough, and took Lil' Johnny to the doctor.
After the examination, the Dr.. said, "Well, his unit is too small.
An old wives tale was to give him two slices of toast each morning,
and his unit will grow so he can hold it and aim straight."
Next morning Johnny jumped out of bed and ran down to the kitchen.
On the table are 12 slices of toast. "MOM," Johnny yelled,
"the Doc said I only had to eat 2 slices!"
"I know," smiled his mom, "The other 10 are for your father."
