Oh, I have eight or nine ideas for this, believe me :D I just need to pick the ones I like best / are least likely to be done by someone else.

Mine will probably lean heavily towards RPF. Right now I fancy either the one where a props guy is sure that Dalek is WATCHING HIM so he disposes of it in the dark of night, or the one where a couple of Dalek Wranglers hilariously lose control of their Dalek and watch it go careeeeeeeeening into the pond and decide not to tell anyone. :D

I totally think the latter is really how it ended up there btw. I've pulled worse shit than that in my time as a set dresser.
