I'd never seen the strip before, but after a run through of the archives, I have to agree - this one's going right up there with PVP, User Friendly, and Gunchello (which I think died in it's tracks.)
It's a very cool strip. I can't remember how I found it, but I do remember reading the entire archives in one wicked slow afternoon at work last winter. I also rather like The Parking Lot is Full sometimes, although it's pretty odd and definitely hit or miss. Not to mention, they don't update it any more, either...
Edit — How could I forget Shallow Grave — this comic (used to be in the Cavalier Daily, UVa's student newspaper) is absolutely uproarious. Sometimes very twisted. Plus, you can't argue with anything that combines Cthulhu, Car 54, and recycling. Well, I can't.
