Mr. Know-It All: The obvious giveaway was when the pianist reached to his left to play bass G-flat chord. Everyone knows Chopin demands C# at that point.

Edit: Several mid-20^th C comics played an invisible piano, a riff on inductance theremin* players who waved their hands over the instrument.

* musical instrument with electronic tone generation, the pitch and tone volume being controlled by the distance between the player's hands and two metal rods serving as antennas.

They also play on a "keyboard" curved in two directions.

A little known fact is that the word "gullible" does not appear in many dictionaries.

Just playing along, I happen to be a decent air pianist.
