Scott Baio made us swoon on 'Happy Days' as Chachi, and then he grew up and helped teach us life lessons on 'Charles in Charge,' but what's the former heartthrob up to now?

Then: 

On 'Happy Days,' Scott Baio played Chachi Arcola, cousin of The Fonz, and guy who was totally into Joanie. Their romance was such a hit that the pair eventually got their own spin-off, 'Joanie Loves Chachi,' but it only lasted for 17 episodes.

Then, from 1984 to 1990, Baio starred on 'Charles in Charge,' playing the titular character -- a 19-year-old college student who works as a live-in babysitter in exchange for room and board. Life lessons were taught and many "very special episodes" were had.

In 2007, Baio starred on his own VH1 reality series, 'Scott Baio Is 45 and ... Single,' and its follow-up, 'Scott Baio Is 46 and ... Pregnant.' (Spoiler: He wasn't pregnant. But his wife, former Playboy Playmate Renee Sloan, was.)

He stuck with VH1 for yet another reality series, 'Confessions of a Teen Idol,' in which former teen idols tried to resurrect their careers.

These days he's the star and producer of the Nick at Nite original series 'See Dad Run.' Loosely based on his own life, the show follows a former actor who becomes a stay-at-home dad.
