Jean-Clade Van Damme was a master of three things in the 80s: kicking people in the face...

splits...

and making REALLY intense faces. 

But he was also pretty good at dancing (and punching people in the face while busting a move) and showcased this in a famous scene from his 1989 classic Kickboxer. To prove to Conan's audience that he can still bust out some signature JCVD moves, he recreated his famous scene, because nostalgia. 

Also, I think Jean-Claude Van Damme is probably the only person on Earth who can wear a hat with his own initials and have nobody question him on it.
