D.J. Fluker recently spent some time at the San Diego Zoo with Bleacher Report. He was having a great time checking out the pandas, giraffes and all of the wildlife. But things got really wild when exercise guru Richard Simmons unexpectedly showed up and took over as the zoo's No. 1 attraction.

Simmons is most noted for his weight-loss videos. But you've probably seen him a ton of times on Letterman or Leno. He just shows up and makes good TV.

Check out the video above to see how shocked the 6'5", 339-pound Fluker was when the diminutive Richard Simmons showed up at the zoo.
