Lost/rare media that you own

One of the many Lost/rare pieces of media that I have is a FYC screener copy of Bee Movie. 
This disc has kind of a weird story. The printing on the disc says that the running time is 95 minutes, but the film on it runs around the same as the theatrical cut. That might be hinting that an earlier cut of the film was planned to be on the disc at some point.

Here's a screenshot of what the watermark looks like:

I have a couple of dvds that are rare (haven't been/weren't online for years) those being the Poko and Animal mechanicals dvds. I also have some dvds that have tv recordings so i guess they might be rare.
