A young couple in Germany placed their newborn for sale on eBay in May, 2008. The ad read: “Offering my nearly new baby for sale, as it has gotten too loud. It is a male baby, nearly 28 inches long and can be used either in a baby carrier or a stroller.” Starting price was one euro [$1.59 U.S.]. The auction ran for just two hours before eBay removed it - no bids were made. The 23 and 24-year-old parents claimed it was a joke. The baby was removed for several days during an investigation, and returned by social services who were conducting home checks. 
Be careful and think before you say something online - not everyone shares your sense of humor and may take your comments seriously.
