You can draw a mustache or a nose on a stranger's picture in a magazine. Or, you could draw a penis on a billboard (be sure to take a picture)!  You can write on someone else's whiteboard without their knowledge.  You can also stick a pen up a pet's tail and watch them try to get it out.  Make sure to have some paper handy to write down the laughs you’ll be getting!
