Did you know LeVar Burton is an authority in contemporary dance? Me neither. After being a total boss on Reading Rainbow, Burton began experimenting with astral planes, other dimensions and paranormal phenomena. Naturally, he became stuck in the afterlife. Instead of crying about it, however, he decided to help the living become better at dancing.

Zack Galifianakis dominates most of this clip, but LeVar's cameo is completely absurd and takes the laughter to new levels. The fact that he's playing the ghost of himself is absolutely amazing.
