It has finally been admitted that Hanna-Barbera named their cartoon bear Yogi in order to play on the great popularity at that time of Yogi Berra. For years they said it was just "coincidence".
Another Yogism: When a waitress asked him if he wanted his pizza cut up in eight slices or six, he said "Better make it six--I don't think Ii could eat eight slices."
"Ah yes, the floor here is made of floor."
