Many years ago I read a chess book which mentioned this Olympiad game where black accidently played Ke7 (instead of Qe7) in Bogo-Indian, and when white played Bxb4, black wanted to play Ke7xb4 (illegal move). That anecdote was always good for a laugh.

Tonight I returned home, and joined the Shield 3 0 (SuperShield) tourney to entertain myself, but my eyes were tired, and my opponents were fast and ruthless. Then in this game below I only found out after a few moves [...] that I had played Ke7 instead of Qe7 ?!?!?! pffff. rofl :)
