Plaintiff: Officer Swanson may I'll remind you that you are under oath. Now please tell us what Mr. Quagmire said he did with the girl.
Joe: *sigh* He uh... said he gave her a Frosty Jim
When you pee into a condom, tie the open end of the condom. Freeze the condom, and then have a girl perform sexual acts with the frozen condom. Hence a frosty Jim.
