A hotel in Finland once put out an ad for “professional sleepers” when they wanted someone to test the comfort of their rooms and blog about it. They must have received a lot of offers!
Also, there was that time when an art exhibition in Ukraine called for “sleeping beauties” (being kissed was part of the job, too.) There was an actual clause in their contract saying that if the woman opened her eyes during the kiss, the pair had to get married. As far as we know, no marriages ever happened there.
