An iPod shuffle that wasn't actually an iPod. It was a cheap brand called Soco and could barely hold ~140 songs. That's probably not the absolute worst gift I've ever received, but it's the first that came to mind.
I don't see any gift I receive as bad, even if it's just a sock or a towel.
A gift is a gift, and the meaning behind the gift worth much more than the actual gift.
