If you are retired and bored:
1 Drive around in a black car with a black hat and pretend that you are a chauffeur.
2 Go to restaurants and pretend you are a food critic for a newspaper to see how many free meals you can get.
3 Walk up to people who seem like they are tourists and pretend you are a tour director and show them around.
4 Set up a fortune teller booth on a busy street and tell people their future.
5 Draw caricatures for people and watch the surprise on their face when they see how you drew them.
6 Sing for pocket change. People will pay you to shut up.
7 Pick people up from the airport and drop them off at random places.
8 Go to the supermarket and open up random items and give out samples to other shoppers.
9 Put a camera around your neck and take pictures of people who look interesting. Conduct an interview and do a photo shoot.
10 Hang out at the train station and have people march and teach them a cadence song.
