When a vampire washes itself, rain will fall from heaven. Thus, when a drought occurs, nobles send all their men to wash, because any of them may be a vampire.
From Agnes Murgoci’s 1927 paper The Vampire In Roumania, as found in The Vampire Casebook compiled by Alan Dundes
This is so amazing to picture. Like ok men, we know PROBABLY some of you are vampires. IT HAPPENS. This is old timey Romania. That’s how it works. So hey don’t worry, no questions asked, personal business is personal business, but if EVERYONE would just go take a shower we would really appreciate it. Thanks.
Damn right this is relevant to my interests.
