Get ready for Year Six of Superosity by Chris Crosby. Wow, that must be a gazillion strips. Or more accurately 1825 comic strips.
On his website, Crosby offers a challenge and a contest:
I challenge you to read ALL 1,826 strips in the archive, starting here. It may be difficult, but if it wasn’t, it wouldn’t be a CHALLENGE (Dan Shive was man enough, and I didn’t even have to CHALLENGE him!). When you’re done reading all 1,826 strips, E-Mail me and tell me so, and I will send you a random SUPEROSITY TRIVIA QUESTION that anyone who has read the full archive recently should be able to answer. If you DO answer it correctly, you will be included in a RANDOM PRIZE DRAWING, and five of those people (assuming there are that many people brave enough to take my CHALLENGE) will be picked randomly to win a PRIZE. I’m not sure exactly what it will be yet, but it’ll be cool, and the first person picked will win a CAMEO APPEARANCE in SUPEROSITY, a strip you have read the full archives of!
