There was a first season episode of one of my fave tv comedies , Get Smart, where a KAOS agent was using special paints that caused a chemical reaction with each other after a certaibn time.
He was delivering them to embassies and government buildings, and then KABOOM! Max & 99 figured out that the paintings were the common denominators and tracked him to his gallery and captured him.
TV used to be good!
That is funny
Come to think of it there have been several artistic villians in TV over the years.
The mad whacko crowd
