After the first week of sex education class, a young shapely teen stormed 
out of the room after the class was over. Encountering a female friend in 
the hall, the friend asked, "Lori, what in the world is the matter with 
you? You look as if you're about to kill someone." "I am !!!" Lori fumed. 
"You just wait until I catch up with that Dennis. All summer long, that 
clown had me convinced that 'foreplay' involved tossing a coin for 
position."
