Seinfeld creator Larry David was on Saturday Night Live this past weekend impersonating Democratic presidential candidate Bernie Sanders. In the show, he mocked last week's debate and David's comments on Clinton's email scandal. "What's the deal with emails anyway? I forgot my password the other day, so they say 'We'll email you a new one.' But I can't get into my email to get the password. I mean, talk about a ball-buster," he said.
