I like a comic which asks you to think (or at least calculate)

School is too long ago for this. 5 of the letters got me into trouble. Luckily they weren't needed for solving the puzzle :-)

Good think the geometry and calculus problems don't matter. heh...

kept me interested during the DP call.

Hmmm.... i don't like it. The gimmick is cool, bu the message isn't. Change one word, and it's fine. As it is, I think it's a negative message.

Okay, so the laugh was worth the work. I still sympathize with the sister.

Shouldn't there be another 23 at the end? ;P

Not here in the U.S., Kerr. Now, if it were a British comic...
