Convicted sex offender Bill Cosby ruffled quite a few feathers on Sunday when he made a post identifying himself as ?America?s Dad? in a Father?s Day message. The Instagram post read;. ?Hey, Hey, Hey... It?s an honor to be called a Father, so let?s make today a renewed oath to fulfilling our purpose - strengthening our families and communities". The 81-year-old was convicted last year of drugging and sexually attacking former Temple University administrator Andrea Constand in 2004.
