Calvin: Take a look at this. Wouldn't you say this is a great drawing?
Calvin: I mean, can you *believe* my teacher didn't like it?! She said it wasn't "serious"!

Sorry for the lack of visual, I don't want to bother with an image (hey I did still type it all in with an iPhone). In any case, Calvin's drawing is barely visible in the strip, it's an intellectual gag (like so much of C&H, my 5-year-old doesn't get it yet).

Why is there not a "protect planet from cometary destruction" progress-beaker on this chart?
