J: Rowan and Martin 4re Instant Insanity Dan Rowan and Dick Martin have yanked the cork out of their barrel of screwball comedy and they're back it their old stand on NBC and crazy as ever. "Verree interesting" was the quickie appearance of Rich ard wi. Nixon in a sock-it-to-me routine, when regulars on the show used the catch-phrase they got the slapstick treatment but when Nixon posed "sock it to me?" as a question nobody dared to give him the works. He was on and off screen in three seconds. The first 15 minutes of the show was like a prairie fire. It moved so fast the laughs and chuckles were almost constant. Then it tapered off. Sixty minutes is a long time to fill at a clicketv-clacketv nace. GOLDIE Jack Lemmnn was in-anH-nnt nf ihp shnur ( giving the impression he was astonished at being trapped in a madhouse. Zsa Gabor contributed little to the comedy and ? Hu8h Hefner, the sultan of the Playboy world, was a dud. j Even Arte Johnson's "verry interesting" characterizations lacked the comedy zip of last season. Pigmeat Markham as "de judge" was hilarious and the female cast is excellent Jude Carne, Barbara Feldon, Goldie , Hawn and Jo Anne Worley were right on the button with J; their comedy lines. Goldie pulled the best gag of the night: "Some movies are for children, others are for adultery." And six gals with scraggly hairdos and ukes did a devastating . takeoff on Tiny Tim. "Laugh-in" is a show that can't miss. It moves so fast the . audience has no time to think. Rowan and Martin's regiment of writers scatter the gags like buckshot. Some of them tickle - the funnybone of one set of listeners, others click with a clif--ferent class. When the show is finished there's been laughs " for everyone. And no comedian can ask for more than that.
