People will, I'm sure, write anything, given enough time. But it's a combo I've heard mentioned a couple times too many.

And I have just realized that what I thought was somebody saying Snape/Umbridge might be interesting was in fact them saying Snape/Tonks might be interesting. Snape/Umbridge is right above it, with the caption "gaaaaah!"

I feel stupid now. But still. Snape/Umbridge. *shudder*
