As frequent Twitterers, we're big fans of @ShitMyDadSays, where a man who lives with his parents turns all of his father's withering comments and insults into Tweets. (Example: "Son, no one gives a shit about all the things your cell phone does. You didn't invent it, you just bought it. Anybody can do that.") So when we heard that he was getting a book deal, we were happy for him. Then, when we heard it was becoming a show on CBS, we had to scratch our heads. First of all, the swear words he uses (including the one in the frickin' title) are part of what makes it so funny, and second... it's a show about a grumpy old guy who berates his live-in adult son? How is that different from half the shows on television? We looked back at some of our favorite abusive TV dads from brilliant but cancelled shows.
