I understand and agree with do chores because you're part of the family, but the truth is George doesn't appear to do much in the way of chores. He's outsourced the lawn care to Georgie, and probably the auto maintenance too. (I would, if I were him.) So what exactly does he do to set an example? Still, I can see how being disrespected bothers him, though he lets Sheldon do it all the time.
He should have talked to Georgie about not ripping off dumb younger kids, though. Oh, Billy Sparks, you poor, sweet, gullible thing.
