Calvin and Hobbes by Bill Watterson for November 22, 1993
Transcript:
Hobbes: Now that the thinking cap has enlarged your brain, you can write your homework paper. Calvin: I concur. Mom: Calvin, dinner time. Hobbes: Uh oh. Wait until your parents see your head! Calvin: I am applying my powerful brain to the dilemma. I know! We'll wrap my head in this bedsheet! That will allay any suspicion! Hobbes: Your powerful brain must know something I don't.
I dunno, I don’t think his head looks any bigger than usual.
