Project ideas for breaking a social norm?

[Alaska]

(1) Cut into the middle of a line by yourself; stay in line for at least 2 minutes.

(2) Ask someone you don't know for his/her seat in a public place (e.g., at the commons or in the library); stay in the seat for at least 2 minutes.

(3) Acting otherwise completely normally, hold hands with a same-sex friend (who is "in" on the project) while you walk across campus.

(4) Surprise 3 of your same-sex friends with a kiss on the cheek.

(5) Applaud at the end of a cashier ringing up your groceries at a market.

(6) Before one of your classes begins, go around the classroom and shake hands with at least 8 people; say "good morning (afternoon)" to them or use other words to welcome them to class today.

(7) Wear unusual clothing to class or another public place (e.g., your bunny slippers to church; your hooded sweatshirt on backwards).
