Same basic structure as "Star Wars Nerds": Get a public collection of freaks and losers, add one rubber dog head, and shake well.
For me, the highlight was when Triumph was trying to coax a stupid answer out of an older woman dressed in a clown suit and carrying a Michael Jackson marionette.
Trying to salvage her little remaining senf respect, the woman archly said, "I don't speak to dogs like you."
Triumph shot back: "Yeah, you wouldn't want to ruin your dignity or anything."
I liked it when he asked the MJ impersonator - with a very strangely sculpted fake nose - if he could sing like Michael, and the guy sang a few lines. Triumph asked if he could moonwalk, and the impersonator moonwalked a little. Then Triumph asked him if he could masturbate while watching "Home Alone." The fellow did not seem amused.
