Richard Simmons is quite possibly the greatest human being to have ever lived, and this video clip from the hit ABC television show “Whose Line Is It Anyway?” is a testament to that fact.

For the uninitiated, “Whose Line” is an improvisation show in which four comedians act out a scene completely on-the-fly with very little direction from the host. Occasionally, they mix up the hilarity with unique games like “Living Scenery” in which an audience member is used as a live prop for the actors to use as they see fit.

Here, the live prop is fitness guru Richard Simmons, who, as far as I know, has no experience in improv, but yet manages to pull off one of the greatest performances in the show’s history.

As you can see, the key to a great guest appearance is testing the players on the stage at every turn. If you force them to react to your unscripted tomfoolery, you’ll nine times out of ten have comedic gold on your hands.

Oh, and it also helps if you play up the fact that you really, really like men.
