Yo-yo Ma is a world class cellist and person. This was my attempt to free him from the extremely tired "Yo Mama" references.
Throw Momma from the Train was a 1987 movie starring Danny DeVito, Billy Crystal, and Anne Ramsey. The movie title was derived from the 1956 Irving Gordon song "Mama From the Train." The song title was derived from Pennsylvania Dutch grammar, as in "Throw Momma from the train a kiss" or "Throw Amos down the stairs his hat."
I originally wanted the cartoon to be "Throw MOMA from the Train," but had absolutely no luck drawing a recognizable version of the Museum of Modern Art, much less figuring out how to propel it from a speeding locomotive.
