In the old days of talk shows, a star would saunter onto the set of something like The Tonight Show, make a few jokes about Madonna's fishnet bustiers, plug their television movie of the week and be done with it. But these days, talk show appearances are HARDCORE.
That's what Heidi Klum discovered when she appeared on Jimmy Fallon's show. Holy shit. The woman is there to talk about Project Runway, but there's no reason why we can't make her work she's a a performer in a Ringling Bros. and Barnum & Bailey Circus show. Why not.
