What's the stupidest thing you ever done on your character?

[Phased]

Back on live as a way to make money I used to haul fine steel out of guk, so encumbered that I moved at a snail's pace, to the vendors in Oasis. As a way to make room for one more I put my Mithril 2Hander(that I recently spent all my platinum on) into my inventory so I could equip a 1hander and shield.

I then proceeded to vendor the Mithril 2Hander. The vendor was full and it did not show up. Then I borrowed money to buy up as much vendor crap as possible, hoping it would appear, but it didn't.
