I've got one similar to captain516's:

One day, my sister took our portable DVD player when she went to go see her boyfriend. A couple weeks later, my mom asked where it went, and my sister started telling everyone that I lost it when I took it to watch movies at work one day. She stuck with story for months.

I think it was about four or five months later, the DVD player shows up back in our house again, in the same paper bag it was in when my sister borrowed it. We asked her about it, but she refused to even discuss the issue.
