Once In A Blue Moon

I just saw a thumbnail of a German clip from 'The End in Friend'. 

Unless there's another German joke that I can't see in there, 'Das Ende der Freundschaft' doesn't sound nearly as lighthearted (and it's not like the English version is a barrel of laughs either.) Surely they could at least try something like 'Schaden der Freundschaft'* or suchlike.

*ok, my German is both bad and rusty, but you get the idea. Perhaps Freundschaden? (unless that means physical hurt, which it might.)
