OMG, Marni, my son, the one who is now a Marine did a similar thing when he was a senior in HS, when we lived in Boxborough. He ripped off his shirt and got our exchange student to do the same thing. Then, they answered the door to the "pitch," and said, "How can we help you?" Those guys went running.
It was pretty funny to see two, half naked skinny cyclists doing this.
