ITT: Tell us your tales of bad traders

It is a well known fact that a TF2 player will come across a bad trader in their entire careers, regardless. Share your experiences of them.

NOTE: Don't call people by their usernames. Only mention them as an anonymous player ("this one guy" for example). It's for the sake of the thread and YOU.

Example: There was this one time where this one guy offered me a dirty Razorback for my Unusual Earbills with Hat Effect

i got a strange silver bot killer sniper rifle for my medi mask and some one gave me a ref for my conscious objector

i gib u 2 rec 4 drty fast lrnr

I once bought a clean fast learner for a rocket jumper. Guy claimed that he didn't have any metal, so he used his only thing of value to buy it.

This story varies between me and someone else

Some guy on a server: Hey Gray I'll buy your scout set for a bud
Me: SURE!!!!!
Me: YES!! YES!! (I gain about 20 keys)
