Calvin and Hobbes by Bill Watterson for February 16, 1986
Susie: Hey, Calvin! Are we near a slaughterhouse, or did you forget your deodorant?! Calvin: Drop dead, Susie! You're so ugly, I hear your Mom puts a bag over your head before she kisses you goodnight!! It's shameless the way we flirt. What's it like to fall in love? Hobbes: Well, say the object of your affection walks by... Calvin: Yeah? Hobbes: First, your heart falls into your stomach and splashes your innards. All the moisture makes you sweat profusely. This condensation shorts the circuits to your brain, and you get all woozy. When your brain burns out altogether, your mouth disengates and you babble like a cretin until she leaves. Calvin: That's love?!? Hobbes: Medically speaking. Calvin: Heck, that happened to me once. But I figured it was cooties!!
