I don’t normally like those emails “friends” send saying you must look/read/think about something but I came across this listing on eBay and could barely contain the laughter.  It is listed as a “useless piece of wire” which may or may not be correct but please persevere and continue onto the description and then the questions at the bottom, it may just convince you to place a bid!

See the auction here.  For when it inevitably gets pulled by the killjoys (!) at eBay, view a screenshot here and read the questions here.  I think this guy deserves his $20!
