I’ve never heard anything good or bad about Bill Cosby, but I worked backstage at an event he hosted once (maybe '91-92) and he was a complete prick to everyone on the crew, except the one attractive girl we worked with. She was about 25 at the time and adorable, and he not only spoke only to her and no one else, but it was sort of embarrassing how thick he was laying it on with her. He was rude and dismissive of everyone else.
