This reminds me of a chess game I had recently:

The opponent blundered his queen twice and asked for takebacks and I accepted both because it's no fun to win this way. Then I blundered my knight, also asked for a takeback but he didn't accept. I just replied "lol" and then I crushed him after he made another mistake where he had the audacity to ask for a takeback again.

Some people have no honor.
