We also had a white elephant gift exchange at work, but the catch was that we could only bring in something that we already had at home. I figured my friend didn't need 15 ornaments (her tree isn't that big), so I took some of these and gave them as part of my white elephant gift. My coworker who ended up getting them is Jewish and clearly had no need for them, so he gave them to another coworker to decorate her office (I'm not sure why only the non-Christians ended up with my very Christmas-specific gift). Oh well. I think they look kind of need as office decorations too!
[Note: I wanted to put a picture of the ornaments in my coworker's office, but she has them hanging on her bulletin board and she has some confidential information and paperwork hanging there, so I can't post it.]
