George and DOG are taking a ride in the car! They stop off at a car wash, which DOG does not like very much at all, but George is here to let him (and us) know that maintenance, while sometimes not a very fun part of life, is necessary and good for your health, your happiness, and of course your self esteem. Doing the necessary maintenance on the things you own, the place you live and yourself as a person keeps you fit and everything running smoothly.
So remember: Be like cat. Be good to self.
