"Do you know the human head weighs eight pounds?"

With lines like this, delivered in an adorable lisp and with refreshing ease, spike-haired cherub Jonathan Lipnicki endeared himself to Tom Cruise's Jerry Maguire, and to movie goers everywhere.

As precocious as Shirley Temple and as impish as Macaulay Culkin, seven-year-old Lipnicki has more going for him than multiple cowlicks and over sized eyeglasses (for astigmatism).

"He's not a Hollywood kid," says Ross Brown, creator of the CBS sitcom Meego, co-starring Bronson Pinchot and Lipnicki."Some of them are so over trained, it reeks of an adult talking. Jonathan is a kid and he acts like a kid." As a four-year-old, though, he did tag along to acting lessons with his older sister Alexis, now ten, who appears in TV commercials.

Jonathan already loves the biz. "I want to act until I'm old," he says. "Until I'm 100."

At home in suburban LA's San Fernando Valley with mother Rhonda, who helps manage her children's careers, and father Joe, a CPA, Jonathan is just another boy on his T-ball team. He does his chores, clearing the table and putting his clothes in the laundry, cares for his dog Edgar, a pit-bull mix, and attends Indian Guide meetings with his father. He has already earned a yellow belt in Brazilian Jiu-Jitsu. Other than acting, Jonathan's only ambition is to be a boxer. But he promises with a bright smile, "I wont bite anyone's ear off."
