TV viewers know her best as Stephanie Tanner on 'Full House,' but, as shown in this clip from 'Today,' the life of actress Jodie Sweetin wasn't nearly as wholesome as it was on the long-running ABC sitcom.

In her memoir, 'Unsweetined,' the child star comes clean on her battle with alcohol and drugs that began after the sitcom ended and ran into adulthood.

The Zack Attack is back! Alas, it was for one night only.

Last night, Mark-Paul Gosselaar surprised Jimmy Fallon on 'Late Night' by showing up dressed as Zack Morris from 'Saved By the Bell' -- complete with giant mobile phone. Fallon's been obsessed with putting together a 'Saved By the Bell' reunion, and Gosselaar (who now stars in TNT's 'Raising the Bar') gamely agreed to participate -- if Fallon can get everybody else on board.

It got us thinking about which of our favorite '90s sitcoms need to hold reunions, like, yesterday. 'The Today Show' already hosted a 'Cosby Show' reunion, but here are some more meet-back-ups we really, really want to see:

Ratings for 'Full House,' which began its run in '87, were low at first, with critics panning the cheese factor of the San Francisco-set sitcom.

(Cheese factor? What cheese factor?)

Running eight seasons, 'Full House' became iconic pop candy for Generation X. Just a taste of what it gave us: eye-rolling references for later dorm-room talks, John Stamos' "bad guys just need a hug" lesson -- and the Olsen twins, adorable-little-Michelle-turned-billion-dollar-empire-controlling entertainment tycoons. Name another sitcom with a track record like that ... Exactly.

Island-dwelling heroes, martini-swilling Ivy Leaguers and autobiography-penning sitcom actors ... we're talking, of course, about TV land's most beloved canine cohorts.
