Greatest Cameo Ever?

Y'know how Stan Lee always makes those crazy, fantastic cameos in all the Marvel movies?  They're priceless.  I would never expect a guy like Nolan to have something similar.  The movies were always a little more on the serious side.  And there's no crazy, iconic figure to use for them.  Or is there?

ADAM.  WEST.  The man could be getting a cameo in the final installment of the epic Bat-trilogy, and I for one support this motion.

Come on, it's Adam West!
