Johnny was eating breakfast one morning

Little Johnny was eating breakfast one morning and got to thinking about things.

“Mommy, why has daddy got so few hairs on his head?” he asked his mother.

“He thinks a lot,” replied his mother, pleased with herself for coming up with a good answer to her husband’s baldness.

Johnny thought for a second and said, “I’m glad you don’t do any thinking. You would look silly without hair.”
