It's pretty simple, you give 3 names and the poster below you picks one person for each role. Try to make it as trivial as possible. Here is an example;
People: Mickey Mouse, Rainbow dash, Obama.
Answer: Mickey mouse shoot, RD shag, Obama marry. etc..
So here is my trio for the next person,
JESUS, GANDALF, YODA
P.S Remember adding your own trio, so the next person can continue the game.. Have fun
P.S 2, If you state your reasons it becomes even funnier
