A nod to the Grand Guignol for Halloween...
Here is a photo of the Randow family (presumably before Gene Randow switched to tramp makeup and set out on his own) inscribed to Slivers Johnson. My guess is that Gene is the whiteface on the right.
It looks to be a variation on Joseph Grimaldi's Sausage Machine but why in the world would you four people to do a quick gag like that and just how does the stereotypical "Mammy" character figure in?
Is she Mrs. Butterworth? Does she bring syrup for the sausages?
I've seen Shrine clowns do this gag and bring kids to tears with worry about the dog. I just don't see a way to do this for kids today without the clowns seeming inhumanly cruel but I'm sure that the Randows were rocking 'em with it back in the day.
