As more and more Americans become tolerant of gay marriage, conservatives are attempting to shore up their defenses against homosexuality.

The so-called "Don't Say Gay" bill, which attempts to prevent any discussion of sexual orientation in elementary and middle schools, is currently on the chopping block in Tennessee, but it's still causing intense debate in Missouri.

Colbert weighed in on the issue on Monday's show, first sarcastically lamenting the shift in attitudes ("Those gays are breeding like gay flies..."), then mock-praising Missouri's Republican leaders who are backing the "Don't Say Gay" bill: "Finding out that homosexuality exists is a slippery slope to tolerating it. Take it from me, when I did Sondheim with Neil Patrick Harris he couldn't have been more friendly or professional, and I will never forgive him for it."

The absurd highlight of the segment, however, didn't come from Colbert, but from a quote by the bill's co-sponsor, Dwight Scharnhorst, who defended the legislation by saying that when it comes to our kids' education, "There is no need to talk about Billy wanting to marry a goat."
