If TV Land really wants to do something useful, the network would not ban “The Dukes of Hazzard.” It would ban reruns of the ridiculous show known as “Walker, Texas Ranger,” starring everyone’s favorite karate fighter Chuck Norris.Speaking of “Walker, Texas Ranger,” no mention of that show is complete without at least a few of those famous Chuck Norris one-liners. I have an obligation:• The Boogeyman checks the closet at night for Chuck Norris.• Chuck Norris was the reason the wheel was invented.
