Lol, cancelled what?!?!? It's still on! Sunday nights, 8:30 EST!

Anyways, yeah I'm pretty sure it's got a very basic script, then the actors can throw zingers in the mix if they want. My favorite by far is Lt. Dangle, just for the way he acts, all the time. I've watched the first 2 seasons on DVD so many times, and it never gets old.
