Calvin and Hobbes by Bill Watterson for August 16, 1993
Calvin: It's past noon! Why isn't Susie walking into our brilliant ambush?! Where is she?! You stay here and guard the water balloons. I'll go on a reconnaissance mission and find out what she's doing. Hobbes: Wait a minute. Why can't I go on the reconnaissance mission? Calvin: Because if you got captured, you'd tell Susie anything for a tummy rub. Hobbes: I might not!
