Animaniacs

The statue of Martin Scorsese is a reference to the fact that Martin Scorsese was the director of "The Goodfellas", which is the basis of the Goodfeathers shorts. Francis Ford Copolla (who is mentioned at the end of the short as another statue for the Goodfeathers to perch on) was the director of "The Godfather" movies, which also influenced the Goodfeathers shorts, including the character of the Godpigeon.
