Don't mess with Jonathan Lipnicki. You know, the adorably moussed moppet from Jerry Maguire who says, "Did you know the human head weighs 8 pounds?" Well, not only does the owlish six-year-old now has his own CBS kidcom, half an hour of innocuous family fluff called Meego. He also just got his yellow belt in jujitsu. Which, as he'll tell anyone within side-kicking range, is the same as a blue belt for a grown-up.

Ask The Lipper about a recent magazine article quoting him as saying, "I hate people," and he gets madder than George Clooney in a roomful of paparazzi.

"I was tired!" the little fella protests during a lunch break in the Warner Brothers commissary. To emphasize his point, he stands up on his chair and waves around a spoonful of marshmallow frozen yogurt. Hey, who wouldn't be tired? Those 8 1/2 hour days on the lot, making deals for a piece of his TV show ("Show me the money!"), then having to work the media all night. So he cracked! It happens to the best of them. Bronson Pinchot, who plays the boy's alien nanny on the show (don't ask), had to explain that there are good entertainment journalists and evil ones. Has the miniature martial artist considered retaliation against the evil interviewer?

"He was mean to me, so I'm not going to be nice to him." Look out: if the tyke gets into action movies, he's got his signature 'I've got your nose' move down. And he doesn't even have to take off his glasses.
