Definitely not. SS bolts, the nazi eagle, the iron cross, the fasces, hitler's mustache, etc are all immensely more recognizeable.

The fact that in the skit they say "we've got skulls on our caps" rather than referring to the actual symbol or even accurately describing it tells you the lack of general familiarity. We all know Nazi's had skulls on their caps, no one knows there are even crossed bones there, nonetheless the particular styling. Normal people don't closely examine Nazi uniforms. Further, this is a comedy sketch playing up the absurdity of the situation for laughs; in reality it was not a Nazi symbol of how evil they were, it was a symbol that had been used in the Prussian and other German armies for centuries and then the Stormtroopers of WW1. In the interwar period it was used by the Freikorps and eventually by the SS, trying to invoke that same imagery. It has become a hate symbol well known amongst white supremacists, but not the general population.
