“Impure thoughts”. That was one of the sins we were taught to say in confession by the nuns when we received the sacrament of Penance.
“It was a sin for you to wanna feel up Ellen. It was a sin for you to plan to feel up Ellen. It was a sin for you to figure out a place to feel up Ellen. It was a sin to take Ellen to the place to feel her up. It was a sin to try to feel her up and it was a sin to feel her up. There were six sins in one feel, man!”
