One good rule of thumb for those of us out there who can't dance to save our lives: don't draw attention to yourself. Sure, you might look like you're choking on something when you try to cut the rug, but if you're low-key about it no one will pay you any mind. One thing I wouldn't recommend doing is sticking some bright, flashy piece of electronics on your shoe.

That's why this Dance Messenger is not for us, my two-left-feet-having bretheren. No, leave it to those people who were born with a natural sense of rhythm. While it might sound like a neat idea to have your feet spell out "dope" or "fresh" or whatever the kids are saying these days, it'll really just make people look at your feet while you dance, which is the last thing you want them to do.
