What's up with the shabby suit? He was always dressed to the nines (Joker style) on the show.

...Maybe he's just coming from a bat-beating.

I'm guessing it was specific to a certain episode. Maybe him going undercover as a clown, or something.

Btw, at ~6'3"he was tall, but not that tall. He's standing forward of the chart, probably abetted by camera angle.

Last fun fact: he refused to shave his mustache for the role, so they simply painted over it, as you can see.

When I learned that, I was amazed that I went my entire childhood without noticing. But then, it wasn't noticeable on old CRT TV's, even big ones. HDTV's, it's glaringly obvious. Like Shatner's stuntmen.

And also the makeup job attempting to hide his lace toupee, in certain shots. XD

i guess

Why does he need a stuntman?
