Calvin and Hobbes by Bill Watterson for September 13, 1989
Calvin: That no-good, rotten Moe! He won't give my truck back to me. The oaf will probably break it, too. Should I steal it back? I know stealing is wrong, but he stole it from me, and if I don't steal it back, Moe will just keep it, and that's not fair. They say two wrongs don't make a right, but what are you supposed to do then? Just let the biggest guy make his own rules all the time? Let might make right? ..That sounds reasonable.
