When my son began elementary-aged Sunday school (Reform Jewish), the kids had a brief religious service and song session each week which parents could also join. One very popular song was "Puff the Kosher Dragon". I don't remember any of the words except, "Little Rabbi Goldberg loved that rascal, Puff".

The next year our rabbi went on sabbatical, and his substitute was a rabbi from a nearby city: a Rabbi Goldberg, who was about 5 feet tall. The kids didn't ask for the song that year. (this said by a 4'11" person).
