To all those boppin' chicks and crazy dudes who get off on his tunes, Michigan deejay Rockin' Robby says, "Keep those calls coming in." But, hey, don't ring between 1 and 2 p.m., dig? That's when Robby's mom makes him take his nap.

At age 5, Robby Naismith works the Sunday morning Top Five slot on his father's 3,000-watt radio station, WFXZ, in Pinconning, Mich. (pop. 5,561). Now a six-month radio veteran, Robby has an eclectic following that includes the elderly (his show follows the Polka Hour) and college students (it precedes the Top 40).

Robby has been rocking—so the story goes—since the cradle, where he liked to kick time to his parents' disco records. But it was only when Robby was 3, and he began spinning platters on his own and imitating the patter of his deejay dad, that his mom, Yolanda, thought of putting her son's talent to use. Robby usually tapes the half-hour show on Saturday and receives a $1 allowance for the effort. So far the kindergartner has had to memorize the spiels that open and close the show: Reading is still a career goal. As far as anybody can tell, Robby is the youngest regular deejay in the country. But that may not be true for long—not if 2½-year-old Annie Naismith, a/k/a Rockin' Sister, has anything to say about it.

Jeff Davis is, admittedly, something of a rara avis. For the past two years the 23-year-old aspiring actor has winged his way across the country as "Seymore D. Fair"—get it?—the promotional pelican for the 1984 Louisiana World Exposition, which concludes November 11. Davis describes his avian alter ego as "a cross between W.C. Fields and Groucho Marx." He has bemused the White House staff by dancing with the wives of Russian diplomats and ruffled the feathers of Bob Hope on a TV guest shot. Davis is used to such flights of fancy. When he signed on at the exposition, he had only recently molted his previous persona as the "Golden Eagle" mascot for the University of Southern Mississippi, where he majored in hotel and restaurant administration.

"Just a country boy" at heart, Davis grew up on a farm in tiny Midway, Miss. Besides the 80 hours a week (for which he is paid about $400) he puts in as "Seymore," he tends bar at a local club and is saving his money to feather a nest early next year in L.A., where he hopes to hatch his acting career. "Acting is something I want to do more than anything," Davis says. "But I'm not going to let it ruin my life. I'll give it six or seven years and if it doesn't work, I'll probably say, 'Well, I'll give it another few years.' "
