Triumph The Insult Comic Dog

Triumph, the Insult Comic Dog is a character puppet performed by Robert Smigel premiering in 1997 on NBC's Late Night with Conan O'Brien best known for mocking celebrities.
Triumph was identified in the early appearances as a Serbian Mountain Hound.
Triumph often puffs a cigar, which usually falls out of his mouth when he begins speaking.
The crudeness of the puppetry behind Triumph — Smigel's arm (and sometimes part of his head and face) is often clearly visible in the shot — has added to the character's popularity.
Triumph's debut was in a comedy skit about unusually talented dogs at the Westminster Kennel Club Dog Show, from which he was eventually banned (though his third visit to the show was by invitation).
