This whole thing kind of reminds me of that "Bob Saget Raped and Murdered a kid in the 1990s" routine. Cosby's continued silence is only making the allegations worse, whether they happened or not, and pretty much ruining what's left of his career.
The joke was Glenn Beck raped and murdered a girl in 1990s, and when 22 women come forward from all backgrounds who only have a commonality that they met Bill Cosby and that they say he drugged and raped them, there's little chance they are all lying.
