The title is a pun on the 1955 film, "Bad Day at Black Rock."
The sequence at the end with Tom and the I-beam would not be out of place in a Wile E. Coyote cartoon. Jones directed both.
The scene of Tom and the glove was a wink and a nod to the character Thing, on the TV show "The Addams Family."
The opening credits are quite cleverly done, incorporating live action with names.
By 1965, the sight of a cartoon character (or a human one, for that matter) in their underclothes was no longer the scandal it was just a few short years before. The old production code was on its final legs by then.
