I saw someone pull out the old "confidence makes a man attractive" thing so I thought, "hmm, how much is that true though? Who's someone who's the far end on the confident/unattractive scale?"

Apparantly, he gets around. A lot.

He split from his wife partly because of his "womanising ways"

His success could be ascribed to his fame, but he claims he was a player in high school too:

Despite his characteristic small stature, DeVito never let that stop him from getting laid. Although insecure in high school, DeVito learned to use his height to his advantage. He firmly believes his size is what makes him unique in Hollywood and to women. "You either say no or I get real lucky," he told the Guardian. Maybe he had to try a little harder, but DeVito asserts he was always "getting lucky" as a teenager.

Which he ascribes to growing up with in a house full of women:

DeVito grew up in a house full of women. And he used to spend a lot of time with his sisters and their friends. DeVito attributes this proximity to ladies to his sexual track record in high school. In an interview with The Big Issue, DeVito said that he "had a big advantage over some guys who didn't understand the opposite sex." He's quoted as saying, "I would tell my younger self to use that advantage more, actually—hang around, listen to the girls more. There are nuggets of knowledge you can pick up from an older sister."

I'm posting this here partly because I read this so now you have to read it. So what do you think? Can confidence make up for being 4ft 10in tall? Is he just BS ing?
