I got caught once throwing spitballs in the 2nd grade. The punishment from my teacher was to stay 1 hour after school and throw spitballs... then clean them up.
She let me draw a target on the chalkboard. I played army for an hour, chewing spitballs and popping up from behind desks to throw at the target. I thought it was the coolest day I'd ever had in school. What a dumb teacher! Then my father came to pick me up, (since I missed the bus).
I got a lot of spankings as a kid, but specifically remember only a few. This is one I remember. Never threw another spitball in school. I guess the teacher wasn't as dumb as I thought.
