It's true. Apparently Bill Watterson's beloved characters Calvin and Hobbes were named after Swiss theologian John Calvin and English empirical and political philosopher Thomas Hobbes. Neither one would have had any use for each other, in my opinion.
This was one of the great strips of all time. It brightened my childhood. However, I was too young to get the subtleties at the time, but I liked it. It's worth a revisiting nowadays.
Watterson never drew, or licensed, the crude drawings of a Calvin-like bad boy peeing on some disfavored symbol, often one of a type of car. Those, in my opinion, are so tacky!
