Here's an interesting true story about art. The Russian Ivan Shishkin painted the landscape you see below. Then his then friend the painter Konstantin Savitsky came along unasked and added the bears. Shishin decided that the overall effect was pretty good, and thanked Savitsky.
End of story.
Except it wasn't.
Shishkin's next painting was called The Crowning of Alexander II. It depicted a church scene of amazing splendor. Savitsky, again unasked, came along and added bears. Shishkin complained to the authorities, barred his doors to Savitsky, then painted his next masterwork, Natasha at Her Bath. Savitsky broke into Shishkin's studio at night and added bears.
Shishkin decided at this point to beat Savitsky at his own game, and painted a large canvas filled with bears. He called it, Take That, Savitsky. The night it was finished Savitsky broke in and painted jackets on the bears. At this point Shishkin retreated to his dacha in Vyra, south of St. Petersburg, and took up bird watching. One night Savitsky stole into his dacha and painted bears on the lenses of Shishkin's binoculars.
Shishkin spent the next two years at a private asylum on the banks of the Black Sea. After his release he retreated to the heavily forested property of his sister's husband. During his daily ramble he happened upon a large black bear. He ran up to it shrieking, "It's you, Savitsky, in a bear costume!!"
The bear, who did not like being accused of being a man in a bear costume, reacted violently and Shishkin died of his wounds on 20 March 1898.
