I know bad jokes are good and good jokes aren't bad.
I even understand your dad was a great joke teller and honouring 'the joke thread' is like honouring your dad and there isn't anything bad about that. Bad jokes were never meant to harm. You should excuse the bad jokes because one mans joke is another mans shining diamond stuck in a goats ass.
Jim often polishes up the archeaic joke which is historicly interesting.
Robin Williams had more bad jokes than George Carlin but they were both funny.
If you don't like a show, change the channel. If you hate a joke, don't laugh but being the humor gestapo is imo offensive.
