Back when Darkrai Lv.X first came out and was actually selling for $100 on ebay: A guy had a Darkrai Lv.X for trade. I offered him $100 cash for it. He said "No thanks, but can I see your trades?". I showed him them and he wanted to trade my tin Lucario Lv.X for it. I looked at him strangly and then we traded. So... yeah. Try and figure that one out.
