Hosting your child's birthday means that you're going to be left with a stack of presents from their well-meaning pals (and their parents), and for the most part, it's all appreciated and all good (especially if it comes with a gift receipt . . . ). But every now and then, the birthday boy or girl rips into their stash of loot only to find something completely and totally bizarre/unwanted/horrific/questionable. Case in point: these nine really, really bad gift ideas. Source: Flickr user Daniel Messer
