Mr. Callahan from Muppets Tonight

[The Claw]

As some of you will remember, in the cast of muppets tonight, there was a charector called Mr Callahan (who you only saw the hands of).
I was wandering if anyone knew where a picture of him can be found (I know that you never see him so I can't get a picture of him) but I am looking for a picture of his arms in a sketch, or even better a video chip from one of the sketches.

Many thanks in advance for your help
