Humor is in the genes

Here’s a snippet of our dinner conversation when I went home for Easter.

My grandmother was telling us about a recent exchange on a bus:

Bus Driver: [talking about his job] It keeps me out of my wife’s hair.
My grandfather: But it doesn’t keep you off the streets.

Zing! My grandmother said that the driver probably went home and told his wife about a funny old man on his bus.

“What old man?” my grandfather interjected.

We all laughed. My grandfather held up his hands and said, “No charge.”
