Dates back to 1999, so may be old to some of you (hell, it's old to me and I hadn't seen it before), but this collection of this guy's random feedback on eBay is well worth reading.
It's particularly interesting to see the variety of responses to his feedback - most people respond with "Who is this guy? Ignore him - he's just fooling around, I don't know, I haven't dealt with him", but some people are cool enough to play along.
Found on uknot, incidentally.
