i still have all my books from growing up, but the box set is gold. i'm reading it to my four year old daughter as bed time stories the last few days, it's funny- i feel like i'm warping her somehow, but a good warping. she loves the spaceman spiff ones the most.
definitely best comic ever. far side is a close second-- pretty amazing what he could do in one panel. i have a gary larson drawing that says "to Mark the nerdling" with a drawing of a caveman sticking his tongue out. my dad played basketball with him when i was a kid.
