Both Fallon and his guest must then dance along to a random song that plays after their lines are read.

On Thursday, Fallon was joined by actor Ken Jeong of “Dr. Ken” and “The Hangover” fame.

The doctor turned comic actor seemed to have a blast with Fallon, even when he had to read lines like “I Ken Jeong in the streets…Ken doll in my pants.”

After that particular line, Fallon and Jeong had to bust a move to “Girls Just Want to Have Fun” by Cyndi Lauper.

By the end of the bit, both Fallon and Jeong seemed winded from all the impromptu dancing. They were able to take a breath at the end when they slow danced to “I’ll Make Love to You” by Boyz II Men.
