I like this but I like real money too.

100 keys + 92 (clean one of http://backpack.tf/stats/Unusual/Taunt%3A%20The%20Schadenfreude/Tradable/Craftable/3005 ) + 28 (clean one of http://backpack.tf/stats/Unusual/Taunt%3A%20Battin%27%20a%20Thousand/Tradable/Craftable/3005 ) = 220.

Evidence: Here's a picture but that'll hardly help. http://i.imgur.com/hwa37LN.jpg Steam's item servers are broken so here's the unusual. http://backpack.tf/item/2036137265 Here's the buyer's backpack at the moment. http://backpack.tf/profiles/76561197992887879 Steam won't let me get a view-at-this-time of my backpack so here it is for any inspection. http://backpack.tf/profiles/76561198005593006 I'll come back later to get a permanent record of my backpack at this time (before I move any items in my backpack).
