I found this sign in a bookshop in Kristianstad, Sweden. And because you have to relax (especially on a Sunday), I thought it would be quite fitting. I don't know whether you will be able to read it properly though, so I have put the instructions below as well!
1. Place [poster] on FIRM surface.
2. Follow directions in circle.
3. Repeat step 2. as necessary or until unconscious.
4. If unconscious, cease stress reduction activity.
