Is It Bad to Enjoy a Comic Strip That Isn’t Even Published Anymore?
There are three games existing right now that bear a striking resemblance to Calvinball: one is cricket, because you can’t understand the rules and it has wickets; one is Australia Rules Football, because you can’t understand the rules and it uses flags; and the other is rugby, because you can’t understand the rules and people get really badly hurt sometimes. Sadly, none include the use of a mask. (Thanks to Metafilter, as always.)
