The dancing robot

"This robot," proclaims the Master of Ceremonies, "is a fully articulated android that has analyzed the dances of a thousand masters! But mostly Fosse and Michael Jackson."

The crowd murmurs.

"Now watch as the leading Dancing Robot Wrangler plays his silent kazoo that only the Dancing Robot can hear!"

A man begins playing a kazoo with visible effort. The robot dances in an undeniably fascinating way. The crowd cheers. The Dancing Robot Wrangler bows. The crowd laughs.
