Zim finally grows impatient with GIR's erratic behavior and decides to lock him into duty mode. With his new very serious outlook on life, GIR comes to conclude that Zim is stupid and a threat to the success of the mission and decides to eradicate him. There's a great creepy chase scene through the local library as GIR hovers along zapping at Zim with his laser-eyes but at the last minute the Squidman / Cop distracts him long enough to allow Zim to turn him back to his normal self.

This episode is actually pretty intense after Zim turns GIR into duty mode. It's not scary per se, but after seeing the unemotional red eyes track in on Zim and seeing all the little GIR faces on the library computers I can see why some people are a bit freaked out by the Bloody GIR pic.

My Favorite Moments:

This episode is one of my favorites and as such it's difficult to pick out a single moment. The final confrontation between GIR and Zim in the snack room of the library is awesome as is the holographic battle training, but I think my single favorite moment is shortly after Zim turns down the remote GIR crashes into the ground and exclaims happily "Hi Floor! Make me a sammich!"
