Calvin and Hobbes by Bill Watterson for February 22, 1992
Calvin: I see you with that snowball! Go ahead and throw it! I'm not scared! You couldn't hit the side of a barn! C'mon, throw it! I dare you! Seriously, you could never have done that if my taunts hadn't boosted your adrenalin. Hobbes: I can only find one of your socks.
