I, too, could offer one - sadly, it's years old and entirely in German, but it was great fun to follow (even though at this time, I didn't have any concept of "wank"). It happened on a site for a webcam watching a stork's nest; there was one middle-aged lady who knew everything much better than the actual ornithologists responsible for the project. Woe to everyone who pointed out she might be wrong about anything. Finally, it ended with a flounce post by the main wanker. Kept me entertained for days.

Good times.
