There are good salesmen in this world, and there are great salesmen. Good salesmen can sell you anything, but great salesmen can sell you anything without saying a word. So obviously, this kid selling his mom on not taking a nap is a great salesman. Well, except for the part at the end where he doesn't actually convince her. Guess you better take that nap after all, kid. The coffee is for closers anyway.
