Waiting for the L the other day, I was reading the LED sign telling me to alert someone if I saw a person acting suspiciously, and I had to wonder, "What does that look like?"

I'd like to see a piece that explores what it means to act suspiciously. When we picture what that would look like, what are we picturing? Do we expect to see some creepy tip-toeing? Maybe a curly mustache? How about shifty eyes? I want to see a dance that explains to me (in a hilarious and satirical way) just what I am looking for.
