Insert sad maniacal laughter here.

Despite dozens of television and movie credits, Gorshin will be forever remembered for his role as the Riddler, Adam West's villainous foil in the question mark-pocked green suit and bowler hat on "Batman" from 1966-69.

"It really was a catalyst for me," Gorshin recalled in a 2002 Associated Press interview. "I was nobody. I had done some guest shots here and there. But after I did that, I became a headliner in Vegas, so I can't put it down."

With eerie timing, Gorshin's final role is in the season finale of CSI, which airs tonight on CBS.
