What's up Doc? The main three phrases which have guided Doc's life, propounded to Doc by his father. Doc's children just called grandpa "GW," and still do.
1. "Use your head for something besides a hat rack." [He was telling Doc to think before he acted and to make good decisions based upon appropriate information.]
2. "If it had been a snake, it would have bit you." [He was not talking about snakes. He was telling Doc to pay attention to what is going on around Doc, rather than to go blindly through life.]
3. "Just because everyone else jumps off a cliff, doesn't mean you have to." GW was telling Doc that because everyone else has something or wants something or believes something or acts a certain way or ???, does not mean Doc should just because of them...whomever the cretins were.]
