“Your mother is a vicious, greedy woman!”

The brother tells him to shut up and go sit down.

After about 5 minutes, the old man stands and walks up to the second brother,

“I sleep with your mother whenever I want!”

Disgusted, the brother tells the old man to bugger off.

A few minutes later, the old man stands and starts walking towards the third brother. All three brothers turn around and yell,

“Dad, go home!”
