This morning, he put the "Today" show cast to dance the "invisible horse" choreography that goes with the song, except for Matt Lauer who didn't appear in the segment. Al Roker and Natalie Morales were the most fun to watch, Savannah Guthrie didn't quite get the moves but she made her effort.

Psy tells his fans to "Dress classy, dance cheesy."

The song reportedly makes reference to Seoul's upper-class lifestyle. The lyrics of the track are reportedly about an ideal girlfriend who knows exactly when to act civilized and when to get wild.
