A gnome is stolen from someone's front lawn. This gnome travels the world and photos of the gnome in different locations are posted back to the address he was stolen from. At the end of the trip he is returned to the front lawn with a thank you note in the letter box.
That's about it for my personal experience although I did date a lady who believed that fairies were real. She had little statues of them all over her house.
I didn't hang around for long
