Dockers has been running an ad campaign, which culminated at the SuperBowl in a field full of chanting barelegged men, urging men to "put the pants back on." Context clearly implies that this means, "Become more manly. Get back in charge."
Considering that most men in most places throughout history have not worn pants (the pants we now know were invented a little after 1800), this is just silly. The warriors of early medieval Scotland were feared all over the island; they wore long tunics, a form of skirt. A few centuries later, the Highland regiments in the British army had a reputation similar to the U.S. Marines today - the Highlanders wore kilts, a form of skirt. For that matter, ever seen a picture of a Roman warrior? Knee-length tunics, with an overskirt made of leather flaps with bronze armor attached with studs. The Roman army conquered its world, and held it for centuries, and they did it in skirts.
If you want to argue about masculinity, self-esteem, and being in charge, then argue about it; but it has absolutely nothing to do with who wears the pants.
