My friends and I took to referring to both Cosby and the Jack the Ripper suspect "Kosminski the Polish Butcher" as "Koz".
Which led to an interesting evening of people doing Cosby impressions muttering things like, "Cuttin' the women," and "Jell-O pudding pops...rapin' the women..."
So now I can't see the man without picturing murdered prostitutes.
