Originally posted by Mo Greene - showman: when Sonny is bonking Lucy at Connie's wedding and Tom knocks on the door to tell Sonny that he's wanted in Vito's study. Sonny says "yeah, I'll be down in a minute", then starts thumping Lucy again. The look on Tom's face as he walks away is priceless!
I think the funniest bit is a few moments later when Sonny comes into the study and has a post-coital cigarette.
