WHERE ARE THEY NOW

CBS; The CW

Arguably, the most successful Sheffield daughter was the youngest one. In fact, Zima — who boasted regular roles on Heroes and Californication following The Nanny — continues to book high-profile projects like The Vampire Diaries. Seems Fran taught her just fine.

Benjamin Salisbury, 'The Nanny' (1993-1999)

CBS; No Credit

Turns out Brighton Sheffield was indeed bright — Salisbury graduated from American University with a degree in Broadcast Journalism following his time on television. But despite a small role in a Numb3ers episode and a Domino's Pizza commercial, Salisbury had only a few projects on his plate. Unless you count family — Salisbury welcomed his second child with wife Kelly Murkey in 2013.

The Sheffields' oldest daughter won roles in films like Panic and The Princess Diaries, but found greater success as a voice actress in projects like Superman, in which she played Supergirl. In recent years, however, Tom has found steady work in film and on TV, appearing in series like The Mentalist and The Minor Accomplishments of Jackie Woodman on IFC. And in case you didn't realize Tom was all grown up, the actress currently has a recurring role in the Showtime series Masters of Sex.

Brice Beckham, 'Mr. Belvedere' (1985-1990)

Surprisingly, Beckham, who found fame as the incorrigible young Wesley on the ABC series, didn't score his next regular role until 2007, when he starred in Vh1's short-lived I Hate My 30's. But Beckham, who is a member of the Namaste theater group in L.A., probably loved his 30s after he went viral in 2012 for starring in "Child Celebrities Opposing Kirk Cameron," a FunnyorDie sketch poking fun at Kirk Cameron's beliefs on homosexuality. These days, you can find, and talk to, Beckham on his charming Twitter feed.

Zachery Ty Bryan, 'Home Improvement' (1991-1999)

ABC; Nikki Nelson/WENN

The Taylors' oldest son, Brad, fared much better. Bryan enjoyed a long post-Home Improvement career as a guest star on series like Boston Public and Veronica Mars. But after appearing in some less-than-quality projects — like Syfy's Thor movie, Hammer of the Gods — Bryan founded his own production company, Vision Entertainment Group, Inc. Tim would grunt in approval.

Taran Noah Smith, 'Home Improvement' (1991-1999)

ABC; Nikki Nelson/WENN

Seems Home Improvement led Smith — who played Mark on the series — to mature quickly. After wrapping the series, Smith left acting, accused his parents of mishandling his $1.5 million trust fund, and married Heidi Van Pelt, a woman who was 16 years his senior, at just 17 years old. But Smith, who has since divorced, proved he was still a bit too young at heart — the actor was arrested for allegedly driving under the influence and possession of marijuana in 2012.

Peter Costa, 'The Cosby Show' (1985-1989)

NBC; Myspace

Costa was a beloved member of the hit '80s series as Rudy's silent friend Peter. But Costa is certainly making noise now — after leaving Hollywood shortly after his run on The Cosby Show, Costa jumpstarted a career in music. Currently, Costa plays for Torrential Downpour, PT Grimm, and Kreptatka Bar Band.

Andrea Barber, 'Full House' (1987-1995)

ABC; Twitter

Surprisingly, the actress also known as the flighty Kimmy Gibbler was already a seasoned actress by the time she joined Full House, having starred in Days of Our Lives for four years in the early '80s. But even more surprising was the fact that Barber cut her days as an actress short following her time with the Tanners — the actress, who now plays mom to two children, retired following the show's wrap in order to focus on her personal life, graduating from Whittier College with an English degree.

Staci Keanan, 'My Two Dads' (1987-1990)

NBC; Nikki Nelson / WENN

The actress who played Carol's oldest daughter, Dana, would most likely be game for a Step By Step reunion. After all, the actress already reteamed with Duffy and Christine Lakin in You Again. But the 2010 comedy wasn't her only turn on the big screen — Keanan, who guest starred in various series like Diagnosis: Murder in the late '90s — turned her attention to film after Step By Step's run was complete. Among the projects on her resume: 2009's Sarah's Choice, 2010'S Holyman Undercover, and her most recent project, 2010's Death and Cremation. Could a Step By Step reunion revive her career again?

Josh Byrne, 'Step By Step' (1991-1997)

ABC; Myspace

Just as quickly as young Brendan mysteriously disappeared from the series without mention (in order to make way for the cuter baby Lilly), the actor who portrayed him, Josh Byrne, disappeared from Hollywood. We'd claim he was still chained in Frank and Carol's basement, but this picture of the actor dressed in costume proves he's alive, and presumably can be seen at your local Renaissance Faire.

Kellie Shanygne Williams, 'Family Matters' (1989-1998)

ABC; Facebook

After Williams' post-Laura Winslow project, What About Joan failed to attract TV audiences, the actress stepped away from the small screen, heading to Washington, D.C., to start a youth arts program called the Kellie Williams Program. Turns out, Williams' philanthropy was dramatic enough — in 2012, it was suspected the Kellie Williams Program might have helped former Washington D.C. councilman Harry Thomas Jr., in a scheme to steal money from the city. Thomas is currently serving a 38-month sentence, but it remains unclear whether Williams was involved.

Michael Ray Bower, 'Salute Your Shorts' (1991-1992)

Nickelodeon; heybower.com

Donkeylips locked in quite the career for himself as a perennial guest star. After his memorable stint on Salute Your Shorts, Bower appeared in series like X-Files, Dark Angel, Bones, and Friends, as Monica's prom date. Roles in other projects like Dude, Where's My Car? and Grand Theft Auto IV — in which he voices Eugene Reaper — make you wonder, dude, where's Bower's massive fame?

Kel Mitchell, 'Kenan & Kel' (1996-2000)
