But who created Yo-Yo Ma?
My first guess was Tommy Smothers. But that was Yo-Yo Man.
Then I did a little research and found that "On October 7, 1955, Yo-Yo Ma was born to Chinese parents in Paris."
So the answer must be Ma-Ma Yo-Yo Ma and Da-Da Yo-Yo Ma.
Very good! Your caffeine level must be right up there.
