Did the boys get the chance to sculpt some female genitals? I accuse the school of discrimination! :-)
Reminds me of a dirty cartoon. Sheriff tells the men to "form a posse." Comes back, they have done some clay modelling. "No, I said form a POSSE!"
The boys all went outside and studied the knot-hole in a fence post.
Or maybe the teacher brought in a ham with the bone pulled out.
(Jokes from hubby’s grandmother. His grandmother was rather graphic in telling Grandpa what he could do with his, uh, member. Hubby was scarred for life after hearing her. )
