Suggestion: IMDb Poll Board's Favorite Cameo

Thanks. You have two images, I assume you mean the one from Batman?

@Jessica​ yes, the cameo itself.

Oh, I didn't realize he made a cameo as a character, not as himself. I guess that's fine, though initially I was thinking about appearances by celebrities who play themselves.

@Jessica​ He played himself not the character Col Klink.

Werner Klemperer as Colonel Klink in Batman (1966), episode 2.26: It's How You Play the Game (1966)

OK, but why does it say Colonel Klink in the cast list for the Batman episode?

@Jessica​ indeed, I am wrong

In a rather bizarre cameo, in Episode 26 of Season 2, "It's How You Play the Game," Batman and Robin run into Colonel Klink from Hogan's Heroes, played by Werner Klemperer. This is bizarre, of course, because Hogan's Heroes was set in a World War II prison camp and Gotham City in 1966 was, well, not that. Also, it is odd to see Batman and Robin chatting happily with a Nazi Colonel (who is in town searching for a spy—after Robin tells him to say hi to Colonel Hogan for them, Klink remarks that is a wonder that Hogan hasn't tried to borrow the Bat-rope to escape from prison!).
