With gay marriage in front of the Supreme Court this week, Jon Stewart had himself a good time wading through the oral arguments on Wednesday night’s edition of “The Daily Show.”

To start, Justice Roberts summed up the argument that giving states “a chance to vote” on gay marriage would make the change more appealing to many people rather than a ruling by the court.

Stewart answered that with a photo of a placard from the infamous Westboro Baptist Church, saying “God Hates Fags.”

“If you don’t impose gay marriage, then folks like this will be more open-minded to changing their position,” Stewart quipped, as the sign changed to “Fags Are Okay.”

Stewart had a go at John Bursch, an attorney arguing against gay marriage, in particular. “First of all let me just say I love your lawyer costume,” he said, later mocking his bowtie.

Eventually, the host let Justice Ruth Bader-Ginsberg make his point for him, quoting her point to Burch: Should old, infertile couple straight couples should be allowed to get married along with gay couples?

“What if a couple of 70-year-olds want to get married, counselor? If marriage is for having kids, why should that be allowed?” Stewart asked. “And when answering, try to step as hard and deep into a pile of dogshit as possible.”
