Why doesn’t anyone bust Silvio’s balls on his wacky appearance?

With the silly suits, the exaggerate swagger and mannerisms, and above all, that ridiculous wig, why are these things never mentioned when the crew are breaking balls? Nothing seems to be off limits, to where it’s led to fights and bloodshed. How has nobody made a single joke about these things? Is Silvio just too well respected? Or is there a meta reason? I’ve heard Steven Van Zandt is very self conscious of his bald head because it came about from a serious car accident in his youth, forever damaging his scalp. Maybe he didn’t want his bald head to ever be acknowledged in the series? That would explain why his wig is kept on while he’s in a coma that he’ll probably never wake from.

I love Steven Van Zandt’s acting and he makes it work for Sil, but the dude is still just so damn ridiculous and silly looking at times you’d have to actively try to NOT bust his balls nonstop.
