I know that bad craigslist ads are a dime a dozen, but if these ever become a pop culture art form some time in the future I submit this masterpiece for your review:
seattle.craigslist.org link
The seller must have had so much go wrong for them in life (some mixture of happenstance, poor decisions, genetics and bad luck) that I actually feel kind of bad they would consider this an acceptable for sale post.
Who knows, maybe they were just having a bad day, but it seems reallly unlikely.
