I made a whole bunch of shower games by downloading this awesome font, and stealing ideas from Pinterest. We played a hilarious game of "he said, she said", but my favorites are the mad libs.
I love mad libs. My friends and I used to make them for each other. I wrote one "marriage proposal" story starring D and K, and took out all the identifying words. And I wrote an advice sheet, that I think is even funnier.
Something about nonsense just gets me :)
