Y'know, I think that really fits your character.
Now, I can't think of anyone at the moment for Dr. Henry Quantos or Pete 'the Chimp' Glover just yet. The first actor has to be in his 50s or early 60s and have white hair, while the second has to be a fairly homely 4'11" short, skinny actor who looks like he could blend in with the street folk... or at least be able to mingle with a few circus midgets (although he isn't a midget himself, just short)...
