Triumph, The Insult Comic Dog Visits Chicago's Weiner's Circle With Jack McBrayer On 'Conan' (VIDEO)

Weiner's Circle, the famous Chicago eatery, is notable for two things: Its rude vendors, and in a distant second, its hot dogs. But it may have finally met its match. Triumph, the Insult Comic Dog.

Conan O'Brien wrapped up his week of Chicago shows by sending a couple correspondents to Weiner's Circle, and the results could not have been more satisfying. First, he sent out "the nicest, most polite person" that Conan knows, Jack McBrayer. The "30 Rock" star appeared earlier this week for a homecoming of sorts, as he started his comedy career in The Windy City when he was a part of the famed Second City comedy troupe.

But McBrayer's friendly nature got the best of him, and he had to bring in back-up. And the rude, cursing women of the hot dog stand had no idea what they were in for.

As soon as Triumph shows up, it's a throwdown for the ages. Insults, slapping and eventually a friendly joining of forces. You're going to want to be sure to watch this one.
