Video: Triumph visits Wiener's Circle

Triumph the Insult Comic Dog

There's plenty of expletive-laden insults being slung around the Wiener's Circle in Lincoln Park at 2 a.m. But this weekend, the verbal abuse was turned up at the hot-dog joint as the notoriously foul-mouthed staff faced off with Triumph the Insult Comic Dog ofConan O'Brienfame.

A publicist for O'Brien confirmed both Triumph – the canine rubber puppet known for ending his sentences with "for me to poop on" – and "30 Rock"star Jack McBrayer were at the 2622 N. Clark St. eatery this weekend for filming associated with the late night hosts stint in Chicago. The publicist wouldn't elaborate on exactly what the pair were doing, but said that McBrayer is slated to appear on Monday night's show – the first of four Conan episodes taping in Chicago.

The appearance was further confirmed by photos that surfaced on Chicago's Reddit page – which can be found here -- that show both McBrayer and Triumph standing at the counter looking ready to order. Or at least attempt to.

Despite the burgers and Chicago-style dogs, The Wiener's Circle is most known for its staff that yells obscenities at customers and throws change in the tip jar. The diner was also featured in a truTV reality series that displayed the antics of both the staff and the late-night customers.
