Everything has a weakness

Little tommy is playing catch with his dad when his father misses a ball that hits him squarely in the crotch. The dad doubles over in pain. Little Timmy runs up to his dad.

Little tommy: What's wrong dad? Why are you hurt?

Dad: The ball hit me in our weakness, son.

Little tommy: What's a weakness dad?

Dad: You see son, everything has a weakness. Nothing is perfect. It just so happens that a man's weakness is on the outside of his body.

Little tommy: Oh, well does mommy have a weakness?

Dad: Yes. But you see, a woman's weakness is on the inside of her body.

Little tommy: Where?

Dad: Inside her head.
