I knew, given DW being DW, that it must have happened somewhere. But if there hasn't been a cracky fanfic involving Yetis in the loos, I feel it's still a valid suggestion. :-D

It's been a while since I've seen More Than 30 Years, but I do think on that occasion Jon says something like "There's nothing scarier than coming home to find a Yeti on the loo in Tooting Bec." which could go either way.

I don't mind whose loos. Just, you know, there should be yetiin-the-loo crackfic. Maybe multi-Era (Eleven Times The WC Was Inconveniently Engaged by a Yeti. Or something. ;-D)
