calvin and hobbes are timeless. not long after our daughter was born, a friend of ours visited and had her at the time "tween" son with her and he was bored out of his mind. i was digging around for something to keep him occupied and grabbed one of my old calvin and hobbes books out of the bookshelf for him and he lit up, saying he actually liked calvin and hobbes. i ended up sending him home with all of my old c and h books that day (one an anthology). he just started college this year and i imagine he (like me) read them all cover to cover many times.
