You mean Keith Carradine? Referring to an actor from Deadwood is indeed Justified.

I guess the closest we'll get is the surprisingly fun "Return to the Batcave" special from 2003.

It's not Mentos, but the fourth Dexter novel had a serial killer offing tourists and posing them to mirror Miami tourism ads.

Funnily enough, he was on the radio this morning in Australia, and mentioned he hadn't taken any acting work because he only gets offered serial killers and himself to play.
