Good ol' Roger just happens to be having a stroll by your local tennis club where you happen to be alone, and practicing serves. He's feeling friendly. "Hey Roger, how's it going?" "Good thanks, you?" "Not bad thanks. Wanna have a hit?" "Yeah, sure". How many points do you think you can take off him? A game perhaps? Personally, I think I may be able to take him to a deuce or something. What about you?
