Animated World of DC Comics: Harlequinade (Batman: The Animated Series, 1994)

When the Joker (Mark Hamill) decides to steal a bomb from a mob auction, Batman turns to the Clown Prince of Crime's on-again, off-again honey, Harley Quinn (Arleen Sorkin, Days of Our Lives), to try to stop the plot.

"Harlequinade" is the episode in which Harley sings "Say We're Sweethearts Again", which we've shown on its own previously.

Edit, 5/22/2020: The video has been deleted. We'll sub in this title card:



Paul Dini's script includes a nod to The Honeymooners. See if you can find it.
