Television networks may have done themselves in in their effort to mount successful new sitcoms while at the same time shying away from anything that might offend "blacks, Hispanics, Muslims, Jews, Christians, gays, women, stutterers, the physically challenged, Tom Cruise if he's working on a movie for your studio, the Amish and even Beverly hillbillies," Washington Post TV critic Lisa De Moraes commented today (Thursday). That may be why ABC has decided to order a pilot for a new series called Cavemen, starring the three actors who appear in the current ads for Geico Insurance. De Moraes quoted a network spokeswoman as saying, "We felt it was a way of doing a social satire without offending any particular group -- other than cavemen."
