HAPPY ENDING: What better Valentine for Chris...

HAPPY ENDING: What better Valentine for Chris and Tim Guiton of Foothill Ranch than to watch the birth of their son Mark all over again on national TV tonight? Mark was born last July before the Guitons could reach a hospital. The difficult, bottom-end-first delivery was performed at their home by county paramedic Bill Lockhart. . . . “He was magnificent,” says Tim Guiton. Lockhart will be their guest tonight as they watch themselves re-enact the crisis on TV’s “Rescue 911” (Channel 2, 8 p.m.)

TOO MANY MINUTES? Do you quickly hit the remote when an infomercial comes on TV? Try watching 500 of them a week. Clare and John Kogler of Tustin told Morley Safer on CBS’ “60 Minutes” on Sunday that’s how many they watch to prepare the “Greensheet”--their successful tips and reviews newsletter on infomercials. . . . They didn’t seem offended when Safer asked, “Why would otherwise reasonably intelligent people watch these things?” Clare Kogler’s response: “I can’t explain it either.”

POST MAYNARD: Baby boomers, remember Dobie Gillis on a park bench in front of Rodin’s “Thinker,” talking to TV viewers about his teen crises with Maynard G. Krebs and Thalia Menninger. Here’s a wake-up call: Dwayne Hickman, who played Dobie, is now 60 . . . . Hickman, a TV director, was at Balboa Bay Club in Newport Beach on Monday to promote his new book, “Forever Dobie.” He enjoyed the reminiscing. Warren Beatty, he recalled, played Milton Armitage, “the stuck-up rich boy. . . . He was perfect for the part.”

DROPPING A BOMBE: On a visit to friends in Orange County, Mark Dorfman of Dallas heard about the baking contest to kick off the new Ghirardelli Chocolate Shop and Soda Fountain at South Coast Plaza. On a whim, he flew back here just to enter his chocolate raspberry truffle bombe in last weekend’s bake-off--and won. The prize: an expense-paid trip to San Francisco. Explains Dorfman: “I love chocolate.”
