He got booed at an Obama fundraiser last month. Here's the first part of the joke. {I think it’s funny on its own but would love to hear the punch.}
"My little nephew came to me and he said, 'Uncle, what's the difference between a hypothetical question and a realistic question?'" Mac said. "I said, I don't know, but I said, 'Go upstairs and ask your mother if she'd make love to the mailman for $50,000.'"
EDIT: FOUND THE PUNCHLINE:
The rest of the joke is: The boy does, comes back and he says his mom said yes she would. So Bernie says go ask your sister if she'd make love to the mailman for $50,000. The boys comes back and says she would too. Bernie says then hypothetically we have $100,000, but realistically we are living with a couple of sluts.
As the joke continued, the punchline evoked an angry response from at least one person in the audience, who said it was offensive to women.
"It's not funny. Let's get Barack on," a man shouted from the crowd, which paid $2,300 each to support the Illinois senator
