They were poking fun at Robert Pastorelli’s character on Murphy Brown.
Another actor who died relatively young.
RIP.
I don’t know this particular episode but Seinfeld used some of the greatest standups in small roles. Sometimes great actors - like the fella who played Bookman in the classic Library episode. His name escapes...
P.S.: Hated Murphy Brown and, indeed, he kicked off young, too.
A heroin overdose will tend to do that.
