Sorry, I don't.
The story I would tell if asked this was solved by the guy I was pairing with. He knew about URL encoding images, which immediately solved something we could have worked for weeks on. I was very surprised and impressed. Of course, now that is part of my toolbox, and I wouldn't think much of solving something else this way.
Sometimes I solve problems easily that others find very hard. I'm glad I could help, but I don't go around feeling proud of how awesome I did that day. I just happened to know something others didn't yet.
This might sound like humblebragging, and perhaps it is. Just trying to explain why I have a hard time with this question.
