Have you seen this new trend where people write their phone number on the instep of their tennis shoes?
You're sitting in a subway seat and across from you one such person opens their legs, exposing the inside of their shoe to flash the number in your direction if you are the type of attraction they are looking for.
In response to this trend, on one of my shoes I have written, "Thanks for the number!" On the other I have written, "You're not my type!"
