Bill Cosby was performing a stand-up show in Canada Thursday night when a woman got up to get a drink. He asked her where she was going and she offered to get him one. “You have to be careful about drinking around me,” Cosby told a woman at his London, Ontario, show, the National Post reported. Not everyone in the 1,500-large audience thought it was funny. One heckler got ejected from the show while yelling out that Cosby is a 'rapist.' Others in the audience then booed the heckler. Cosby has been dogged by claims he raped or sexually assaulted dozens of women over several years, but the funnyman has largely remained quiet on the subject.
