Not to get all Jerry Seinfeld on you ass, but "What's will all of the people not wearing pants?" First it was Madonna on her Stick and Sweet Tour (gross title by the way)... http://www.stuff.co.nz/images/750849.jpg
Then Beyonce and Justin Timberlake (Beyonce really wore that while performing - by herself)... http://www.youtube.com/watch?v=M5qx-MVrXfk
...and then the illustrious Lady Gaga (I've seen this in person)http://www.angelawieland.com/images/portraits/portraits-14a-lady-gaga.jpg
When did pants become optional? I understand, you know, swimsuits....but other than that, I'm not sure I find this trend appropriate. Would you show up to a bar, club, Target or work without pants? Now they need to change the signs to say: "No shirt, no shoes, no pants, no service".
