Der Witz ist um die Ecke

I think this means that somebody missed the joke (literally the joke is around the corner). Only this time the joke was on me. Thought I was funny when being home and a good girl last night going to bed early, knowing that CG would come in late and most possibly drunk. Left a post-it on the wine bottle in the fridge saying "pee". Apparently he came home late, but not in the mood for another drink and went straight to bed. So much for trying...
