When I was in the third grade, we had a drinking fountain with four spigots. During recess, kids would chant "coffee, tea, sodapop, pee" while kids were drinking from it. Of course, you didn't want to be the one drinking from the "pee" spigot, or else you would become the laughing stock of the playground. You certainly didn't want someone pointing at you and saying "he likes to drink pee!" That's the sort of thing that can scar you for life. Not that it ever affected me. My therapist tells me it has nothing to do with my social anxiety disorder...
