He's Doing It Again

My dad. This is what he does: He tells you all the jokes that his friends forward to him on the internet, and then if he forgets one, he asks to borrow a laptop and starts going through his email, reading them aloud.

He's been at it all day long.

"Did I tell you the one about the dog urinating?"

"Yes, Dad, you did."

UPDATE: It's 8:55 and he's still reading jokes.
