Where to buy Kryptonite in Munich

Some superheros have moved into the apartment above mine and their endless humping at the wee hours in the morning is keeping me awake.
So I reckon spraying some kryptonite based paint on my ceiling may quell their passion and I can get a good night sleep, so where can I buy.

Here are various neighbor discussions, some of them about noise. My standard advice in cases such as yours is to open your windown and groan and moan and scream, "Ja, Ja, Jaaaaaah!" right along with them.
Get in touch with your other neighbors, ask if they feel bothered as well and time your responses so you all join in at the same time. Should work a charm.

P.S. Post your address so we can lurk in the shadows and enjoy the spectacle.

Next time you see em in the hallway just say something like 'Hats spass gemacht gestern Abend.'

Tape it and play it back real loud around breakfast time.

Please remember to digitise it and make it available on here though.

Can't beat them, join them.
