My whole family consists of Calvin-and-Hobbesaholics.
We have catch-phrases that we use all the time, including "Muchas smooches por El ConKISStador!"
We also admire Spaceman Spiff, and would love to get up a game of Calvinball sometime.
From time to time I like to look at my cat while she's asleep and notice how the fur around her mouth looks just like Watterson drew it, with the broken line to indicate fuzziness.
Watterson was a creative genius, but I think I prefer to have had it end when it did, before it became stale, or he became too burnt out or disenchanted. He went out at the top of his game, which is more than you can say for Garfield or, sadly, Peanuts.
