My youngest two siblings have this game where they pretend every stranger we encounter is either The Famed Welsh Assassin or one of the henchmen of the Famed Welsh Assassin and none of us know why
They used to enjoy pretending in the car that we were being chased by Vladimir Putin. They had a song they would sing about Vladimir Putin for this occasion
These are the same siblings that, in their ongoing storyline and worldbuilding for their LEGO characters, have an evil corporation called FriendlyBiz ruled by an evil clown named Jeff Bozo
