Bill Maher went on yet another rant against the tea party movement Monday night, calling them “sad unfortunate people” who are “corporate America’s useful idiots.” The comedian and HBO host said he’d “have more respect for them if they knew a thing.”

“I don’t have any respect for the teabaggers, and I do call them teabaggers, even though they hate it,” Maher said during an appearance on David Letterman’s show. Then he made them an offer: “I will stop calling them teabaggers when they stop calling it Obamacare.”

CBS silenced out the word “teabaggers” each of the three times Maher said it.
