Bill Cosby Speaks Out ... But He's Impossible to Decipher (VIDEO)

Bill Cosby is finally addressing the sexual assault allegations that have dogged him for years, but his explanations are bizarre and incomprehensible.

The questions were on point. "Nightline" reporter Linsey Davis asked Cosby if he's thought about how he'd deal with young people who only know about the lurid allegations ... Cosby's answer is gibberish.

Ditto questions about the allegations overshadowing the current message he's trying to send to raise awareness about underfunded schools in Selma, AL. Good luck with the answer.

And then Cosby's asked about his legacy.
