Disclaimer: Although I have used eBay myself from time to time, I did not personally find the item being auctioned at the link below. It was forwarded to me via email by a friend with an extremely good sense of humor. I can not however make any presumptions about how he came to find this item himself. My policy in such matters is simple: Don't ask. Don't tell.
Any auction description that begins with “You are bidding on a mistake“ has to be good!
Check out this auction for an old pristine pair of men's leather pants. It's one of the funniest eBay ads I've ever seen.
There's no telling how much longer this ad will be available online given that the auction actually expired over a month ago, so if it's no longer active, I've saved a screen capture of the ad as it appeared today.
