Danica McKellar, the object of Fred Savage's boyhood love in The Wonder Years, is showing off her grown-up side, stripping down and baring plenty of skin for Maxim's June Hot 100 issue on newsstands now.
What's does the former child star, 35, think is hot?
"Confidence is one of the sexiest things in guys and girls," says McKellar, now married with a baby on the way.
But McKellar, who earned a math degree from UCLA and wrote Hot X: Algebra Exposed! to "help girls not be afraid of math," also finds brain power quite appealing, too.
"If a guy is skilled at anything, that's attractive," she says. "There's something very primal about that, and, sure, it can be as simple as figuring out the tip quickly."
