DRM

"I created a DRM scheme that does make sense."

"What does it do?"

"It lets only true fans buy and listen to music."

Music

"What? It's not music law. It's music theory. It's just a theory! Get it?"

Harmonica

"It's a state of the art harmonica, made according to the latest industry standards."

"Really? What's special about it?"

"It'll give you an electric shock if you play anything copyright protected on it."
