Dilbert and Peanuts are two comics that I've seen both on TV and on paper and really enjoyed because of a wide-range of characters and each has special behaviours and personalities that make the comics very well worth reading.
calvin and hobbs and dilbert. if anyone were to say anything else, I'll have to call the nuclear chimpanzee commandos on them.but that isn't going to happen is it?
I like Pearls Before Swine too. Especially the crocs and their failed attempts to eat Zeebah. Aside from PBS, I don't really read a lot of comic strips.
My favorite ones are definitely Calvin & Hobbes and Garfield comics. I have "The days are just Packed" from Bill Watterson, Calvin & Hobbes creator. I love reading it before I go to bed. And Garfield comics are also cool, once my friend lent me some of his comics and I read all of them in a day.
don't forget about Doonesbury! and yup, i used to love Calvin, but I've read them all now i'm reading them in original language. also, peanuts, garfield, pearls before swine, dilbert, get fuzzy. but Calvin & Hobbes is the best.
