Fortunately/Unfortunately
Players concoct wild stories by taking turns using statements that alternately begin with fortunately and unfortunately. For example:
“Fortunately, the amusement park isn’t going to be crowded today.”
“Unfortunately, it’s because Bigfoot scared all the customers away.”
“Fortunately, it was just a man dressed in an ape costume.”
“Unfortunately, the real Bigfoot is suing him for impersonating a Sasquatch.”
