Under Grumpa's Hat

An old man was eating at a truck stop, minding his own business, when three dangerous-looking bikers walked in.

The first walked up to the old man, pushed his cigarette into his pie and then took a seat at the counter.

The second biker walked up to the old man, spit into his milk, and then took a seat at the counter.

The third walked up to the old man, turned over his plate on the table, then took a seat at the counter.

Without a word of protest, the old man quietly paid and left the diner.

One of the bikers said to the waitress, “Humph, not much of a man, was he?“

The waitress looked out the window and replied:

“Not much of a truck driver either. He just ran over three motorcycles with his truck!“

Moral of the story: Don’t piss off an old man, as his revenge may not come in the form that you would have expected. Wisdom and experience have their virtue.
