You can kiss a strange woman and marry her if her eyes open
Canadian-Ukranian artist Taras Polataiko has a work showing at the National Art Museum in Ukraine with women playing the part of the sleeping beauty. Sounds straightforward enough, except that both museum-goer and museum-sleeper are bound by contract to marry each other if the latter opens her eyes after the kiss.
As someone wisecracked in a comment on the article page, “I was gonna get a Russian mail-order bride until I saw this. Now, I need to get to the Ukraine in the next two weeks & can get married for just air-fare. That should save about $10k.”
