Wanda: I'll have the sausage stuffed clam tonight.

Randy: What's that?

Wanda: Need I explain? (Makes a gesture with her hands of one finger going in and out of a cavity made out of the other hand.)

Randy: Ohhh! (Exposes his instantaneously erect penis.)

Wanda: You got the idea now cock me hard!
