Don't forget 'Dilbert'.
Dilbert isn't a comic strip. It's a documentary.
For years, I'd read the occasional isolated "Dilbert" strip and think, "Eh -- mildly amusing."
Then I read though a couple of Scott Adams' "Dilbert" books, where ongoing series of the strip were all in one place. Couldn't stop laughing!
Got a chance to talk with Adams once on a call-in talk show. Asked him if there was any rhyme or reason behind his choice of characters like "Bob the Dinosaur" or "Catbert" or "Ratbert," etc. He said there wasn't.
