The main objective was that Davis enjoy his experiences at the barber shop, and he's having a good time going to Chaffee. Davis noticed a photo of a race car on the wall, and it turns-out that Lisa "sponsors" 3 cars that race at Tri-State (free hair cuts for the drivers and she gets a sticker on their car). So the little boy has some incentive to get his race car driving thing started -ASAP!
