I organized a funny boxing-event in cyrodiil with a partnerguild years ago.
That was in the time when the dueling system wasn't implemented. So we (daggerfall) met the other guild (ebonheartpact) in Cyrodiil. Everybody had to take their clothes off and take their abilities off the bars. And then: boxing until death.
The funniest part of this was actually the guild-boxing. So we had 10 on our side and 10 on the other side and then we ran into each other boxing everybody.
Need to find that video again, it was amazing. That was an evening full of laughter that I will never forget.
ESO has a lot of funny memories for me, but that was the most impressive for me.
