Calvin and Hobbes by Bill Watterson for December 19, 1987
Calvin: They say Santat knows if you've been good or bad, but what if someone had been sort of both? I mean, suppose some kid tried to be good...at least, well, most of the time...but bad things inexplicably kept happening? Suppose some kid just had terrible luck, and he got blamed for a lot of things he did only sort of on purpose? Hobbes: Who exactly might we be talking about? Calvin: This is a purely hypothetical case, Mr. Smartypants.
