Pancakes

Brenda and Steve took their six-year-old son to the doctor. With some hesitation, they explained that although their little angel appeared to be in good health, they were concerned about his rather small *ahem*.

After examining the child, the doctor confidently declared "Just feed him pancakes. That should solve the problem".

The next morning when the boy arrived at breakfast, there was a large stack of warm pancakes in the middle of the table.

"Gee, Mum" he exclaimed, "for me?"

"Just take two" Brenda replied.

Spoiler:

"The rest are for your father".
