Although Alfred splits Archer's arrows repeatedly in part 1, at the end of this episode he misses a relatively easy shot to hit an apple.
This is the first time Bruce Wayne is out of his Batman costume while in the Batcave.
Maid Marilyn, as with many past villain's moles, decided to help Batman by providing him and Robin with swords. However, there is no reason why she decided to do it.

The Archer: Impossible, my dear Sheriff of Gothinghamton. My number's unlisted!
Alan A. Dale: I like that cape, Batman. Very chic. Wash and wear?
Alan A. Dale: I do so wish he'd get on with it. Sounds as if he's electioneering for governor.

The better part of the previous segment had Maid Marilyn supply Archer with a special audio machine, which was purloined from "a castle of a television producer who makes alleged comedy programs," and emitted applause every time Archer committed an act of treachery.

One of the musical's signature songs is Ya Got Trouble, with the refrain, "You got trouble right here in River City!"
Et Tu Brute
