For me the worst item I have been given as a gift, is a Wally Szczerbiak action figure, that I was given THIS YEAR long after he was traded.

For one thing, I am way too old to start collecting action figures(I have none besides this Wally one...), and for another Szczerbiak was one of my least favorite players to ever wear green. I would have been okay with getting the gift if it was Delonte, Gerald, Big Al, or Gomes, hell I'd probably even like a Telfair figure better than Wally. Of course, I said nothing negative about the gift upon receiving it and said thanks, but in my head I was thinking, "WTH am I going to do with this?!"(Should I unwrap it now and use it as a voodoo doll?)
Maybe you've been lucky enough to avoid being given a bad gift, and have instead made a purchase that you later regretted. Do you have anything Celtics related that's worse than my unwrapped Szczerbiak action figure?
