While I normally have no problem with off color jokes, I do have young grandchildren and great grandchildren that do have a budding sense of humor. They are with me sometimes when I log on to CZ. I have stopped checking the joke forum if any of them are with me. I realize that sooner or later they will hear the same things at school or log on to a site when I am not around. I simply do not want them to grow up seeing me as a dirty old man that loves nasty jokes and checks them constantly. Most notably the one recently where Obama called someone a "white mf", 'twasn't fun explaining that one to a 7 year old.
How about an "Off Color" Joke forum, or a political joke forum. I get amused with the political jokes, but I usually put them on the political forum.
