Have a conversation about politics
Tell a stranger that they look exactly like your deceased family member, and then explain that he/she died in a very creative or gruesome way, describing every detail.
If you own a Bluetooth, look someone directly into the eye and ask, “How’s your day going?” when they answer say “sorry I wasn’t talking to you”
If you encounter an asian in a bathroom, take the stall next to him and randomly exclaim “Its true!” leaving him confused and most likely angry
Approach a random person hysterically laughing and ask to get your picture taken with them, find the most average person (preferably female) for best results
If you’re driving and you see someone walking, or running without an ipod on, yell “WHAT ARE YOU DOING” at them making them self conscious and uncomfortable
