The electrical switches that contestants on the old school Nick show "GUTS" had to hit on their way up to the top of the Aggrocrag. If the contestant missed an actuator, they would be forced to go back down and hit the said actuator before they were permitted to finish. If anyone missed an actuator and had to go back they were pretty much out of luck; no chance of winning the piece of aggrocrag, unless they totally pwned their opponents in all the other challenges.
"Dude, the guy in purple totally missed the second actuator. He is totally screwed now. That sucks."
