One I found, "The single greatest Wikipedia edit of all time": there's a penguin and a bloke playing the bagpipes, the picture was taken in 1904. The caption says 'Piper Kerr, a member of the Scottish National Antarctic Expedition, plays the bagpipes for an indifferent penguin, March 1904'. Fair enough.

Then some bright spark edited 'Piper Kerr' to 'Piper Kerr (right)'!

As if you needed to be told which figure was the bloke! I couldn't stop laughing!
