Calvin and Hobbes by Bill Watterson for December 09, 1995
Transcript:
Susie Derkins (friend): I see you, Calvin, and you'd better not throw that snowball! I'm mailing a letter to Santa right now! Calvin: Is the envelope already sealed? Susie Derkins (friend): Yes, but I could write a P.S. on the back. Calvin: Do you have a pen? Susie Derkins (friend): As a matter of fact, I do! Calvin: I'll bet she's bluffing, but this isn't the time of year to tempt fate.
Calvin’s got a good arm to hit her from that far away.
