Conan O'Brien has been doing his show live in Chicago for the past week and what trip to Chicago would be complete without a visit to the famous Weiner Circle. The Weiner Circle is known for its tasty hot dogs (and its rude workers who berate the customers). So as an experiment, Conan sent two people to try it out. The nicest person he knows - '30 Rock' star Jack McBrayer - and the meanest person he knows - Triumph, the Insult Comic Dog. Hilarity ensues.

The schtick of the Weiner Circle - that the staff yells and insults you while you place your order - is the perfect foil for both McBrayer and Triumph. While McBrayer struggles to keep up with the bluster of the Weiner Circle staff (there are so many *bleeps* it's hard to keep up with what they're even saying to him), he brings in a ringer: a professional insult comic (dog).

In the scene you see pictured above, Triumph is shouting at the blue-haired woman: "Listen to your mouth. Do you kiss your pimp with that mouth?"  It goes downhill from there.

For all you Triumph fans out there, you're gonna want to make sure to watch this one. Check out the full Triumph the Insult Comic Dog clip below!
