On Wednesday night, Brian was invited to the Colbert Report to speak with Stephen about the New York City mayor's race and more. A few of Brian's takeaways:

• The entire staff is gracious and professional. Some are even listeners!
• They pre-interviewed me on the day before, which I guess helps Stephen and the producers write jokes. 
• Stephen himself was very nice, touching base with me out of character before the taping.
• It's a real trick to be a guest on that show, because you're there to deliver some kind of real information or opinion, but wrapped in the context of talking to the fake blowhard character.
• The best advice I got from his producers was to talk to him like he was some rich drunk idiot at a bar.

Below is video of the appearance, and a few behind-the-scenes pictures taken by the BL Show staff, who also got to attend the taping.
