Here's some info about Eddie Lawrence, the comedian who created the character called The Old Philosopher, and made "Is that what's bothering you, Bunkie?" a catch phrase during the 1950's. I think he's still alive, and he made an album called "The Jazzy Old Philosopher" in 1994.

And here's a transcription of one of his skits: "A Merry Old Philosopher". There were many variations on his basic theme.
