Better than Tom and Jerry

Bernie Zaslav sent me this puzzling cartoon this morning, which has a possible solution in this cartoon (since a trebuchet is sort of like a catapult or piano action. (Raymond Scott, who did write a lot of music that was used for cartoons, had nothing to do with the Tom and Jerry cartoon.)

But I found this Victor Borge version of the same Hungarian Rhapsody which is even funnier than the cartoon.
