Any kid who grew up in the '90s secretly wanted a piece of the Aggro Crag from the hit Nickelodeon game show "GUTS." To win the game, contestants had to beat two other opponents by competing in four "extreme" sports, plus climb to the top of the Aggro Crag. Harnesses, wave pools and obstacle courses were the usual. Oh, and it had a very catchy theme song.

Unfortunately, the closest most kids got to taking home a piece of the Aggro Crag was if they won the Super Nintendo game based on the show. The video game was awesome, but definitely not the same as physically holding your badass trophy in front of hundreds of screaming fans on TV.

"GUTS," which was later called "Global Guts," ran on Nickelodeon from 1992-95. Mike O'Malley was the show's enthusiastic host, and Moira "Mo" Quirk was the by-the-book referee.

Mike O'Malley then...

...and Mike O'Malley now.

The "Glee" Years

O'Malley hosted the short-lived Nickelodeon game show "Get the Picture" in 1991, and then went on to host "GUTS" a year later. In the early '00s, he starred on the comedy "Yes, Dear." From 2009-15, he played Kurt Hummel's (Chris Colfer) father and Finn Hudson's (Cory Monteith) step-father on "Glee," receiving an Emmy nomination for "Outstanding Guest Actor in a Comedy Series" in 2010.  You can listen what he had to say about shooting the "Glee" episode honoring Monteith here.

Film and TV writer

He's also a screenwriter, writing the script for "Certainty" and TV episodes for both "Shameless" and "Survivor's Remorse." FYI, O'Malley is also the creator of "Survivor's Remorse." It's interesting to me that O'Malley wrote for "Shameless," since that's about as far away from Nickelodeon as you can get. Just goes to show how diverse of a performer and writer he is.

Moira Quirk then...

...and Moira Quirk now.

Why yes, that is a piece of the Aggro Crag in her Twitter profile picture, because duh.

The Nick Years

Quirk was heavily involved with Nickelodeon during the '90s and '00s, but not just with "GUTS." She, along with O'Malley, was a celebrity guest judge on "Figure It Out," another popular Nickelodeon game show. You could also find her — or at least her voice — on "Hey Arnold!," "The Wild Thornberrys" and "My Life As A Teenage Robot." On her website, Quirk admitted she did climb the Aggro Crag, and "it was awesome." You can check out some Nickelodeon behind-the-scenes stuff here.

"Dirty Work"

In 2012, after lots of voice-over work, Quirk returned on-camera in the TV comedy series "Dirty Work." She wrote on her website, "Loved the cast! Loved the crew! Loved that it was the first ‘new media’ series that won an Emmy! How cool is that?" Very cool, actually. She's also written for several publications, including Wondertime Magazine and Baby Talk Magazine.

Yep, it looks like they still "have it." Fingers crossed The Splat decides to bring back this classic Nick game show in the near future!
