Scott Baio – who played Chachi on Happy Days, Charles on Charles in Charge, and … um, that’s pretty much it, actually – is currently shopping around a tell-all memoir, BaioWatch: How I Dated and Loved Hollywood’s Most Beautiful Women and Ended Up Alone, about his life as a former star and notorious ladies’ man. According to a story on canada.com, Baio ended a relationship with Canada’s own Pamela Anderson when she expressed interest in a breast-enhancement.

“One day Pamela came home and said, ‘I’m thinking of getting my boobs done.’ Admittedly, I was surprised. My initial response, ‘Reduced?’ She already had large, beautiful, natural breasts,” [Baio] recalls. “At that moment I knew our relationship would soon begin to crumble. Pamela had finally gone Hollywood – or whatever it is that happens when a woman becomes a hot celebrity.”

Baio also talks about losing his virginity to Erin Moran (who played Joanie on Happy Days) and being asked by Liza Minelli to father her child.

On the evidence, it’s hard to say what Baio will get first: a new girlfriend or a publishing contract, though it’s probably fair to say that no one was sadder to see Judith Regan go.
