The exact same electric chairs to which Batman and Robin are strapped inside the moving van are used again in a Season 2 episode called Ma Parker.
(edit) The Joker's Las Vegas bookie is named Pete The Swede. (edit) Kip King later provided the cartoon voices of Shecky on Hanna-Barbera's 1983-84 series call The Biskitts. (edit)

Nick: You stupid hunk of cheerleader...the guy's a phoney! Already had two packs today. My blind grandmother could see that that kid never had a single weed in his hand in his life!
Susie: Good gravy. (edit) Nick: She's dead.
Joker: Are you sure?
Nick: Sure I'm sure, I saw them loading her onto a meat wagon from the city morgue. The Boy Wonder was bawling his head off. (edit) Robin: Holy Benedict Arnold! Suzie! Chief Cheerleader, a member of The Joker's criminal gang! (edit) Joker: [laughing] Have a sneeze on me, Batman!
[Joker administers sneezing powder upon Batman, which has no effect.]
Batman: No use, Joker! I knew you'd employ your sneezing powder, so I took an Anti-Allergy Pill! Instead of a sneeze, I've caught you cold! (edit)

Not for the first time, one wonders exactly where Batman keeps his Bat-Shield. It folds into quarters, which still leaves you with a piece of flat plastic about a foot square. Conveniently Adam West vaguely tucks it back behind his back and then the camera cuts away. (edit)
