And subtract one... 'Fuller Grime' was played by Gene Roth.
You're right. I apologize for my goof. Gene Roth appears as Fuller Grime in the same short, but the supporting player I had in mind is just credited as "Crook".
I need to find a few more shorts where our supporting player actually had a name. He is in so many, but I didn't realize how many times he appears without a name until I started looking up some of his roles.
How about a hint: In the short where he is credited as "Herman", his name is not spoken, but it appears in the logo on the driver's side door of his car (near the beginning of the short).
