I was hoping to learn this too.

We're left to speculate.

...But I hope it was Weird Al's first film, "UHF".

I assume it was actually the last batch shipped.

I suppose they could have figured out the last fulfilled order though.

Right, I guess I should have specified which DVD was shipped with the last incremental order ID?
