Calvin and Hobbes by Bill Watterson for January 22, 1989
Calvin: Ok, let's see...if the wind is blowing north-northeast as 6 MPH, and I throw the snowball due west at 90 MPH with a slight top spin... Ha! Susie didn't even hear me sneak up! Now I'll cream her cranium with a barrage of snowballs! Darn these cross breexes! She didn't even notice! Susie: You're the worst shot in the world, Calvin! If it wasn't for gravity, you probably couldn't even hit the ground! Calvin: I did it! I did it! Just when it really counted, I did it! Ha ha ha! Right in the kisser! Ha ha! Bad news, Mom. I promised my soul to the devil this afternoon. Mom: Oh? That recently?
