I think I became a trash for Cesare/Jane from The Cabinet of Dr. Caligari. 

The main culprit is this video:

There are also some fanworks with this couple on deviantART, another vid on YouTube, and it seems that someone made a(n amateur?) musical based on this movie, in which their relaionship is explored in a romantic way.

BTW, @hailielle, it’s your fault ;) - I’ve read your comment below my reblog of gifset from this movie and i had to check, how many people ship these two :D
