Personally for me, the most "Bitcoin-ish" things I have ever done is spending 27 days, 11 hours and 23 minutes minus AFK time on Bitcointalk to obtain the rank Legendary. With the hope that one day I will be able to put it inside my resume - alright, just kidding.

What's the most Bitcoin-ish things you have ever done?

eg. laszlo for being the first person to buy pizza with Bitcoin
