On Tuesday’s show, Stephen Colbert poked Rep. Michele Bachmann and Bob Vander Plaats, the leader of an anti-gay Iowa group that she’s in bed with. Plaats believes that same-sex marriage is as dangerous as second-hand smoke, and Colbert works that analogy to comedic extremes.

Watch “Threat Level: Rainbow” (warning: adult humor)

P.S. Jon Kyl is gay. (#NotIntendedToBeAFactualStatement)

Note: If you haven’t seen the Pap Smears at Walgreens episode where Colbert first exposed Kyl’s lie and ripped Fox hosts for their ignorance of women’s healthcare, go watch it. It’s not about LGBTs, but it’s one of his funniest.
