Unless some zoologist can dig up a weird exception, humans beings are the only living creatures who wear clothes. We are also the only beings who laugh, for humor is the exclusive property of humanity and consists, in its most essential form, of the ability not to take oneself too seriously. One of the reasons people laugh is because we know, deep down, that because we wear clothing we are all something in disguise. Trussing, tight and constricting, conventional male attire offers special cause for reflection. Consider men's trousers, garments totally unsuited to male anatomy.
Men are constantly aware of their trousers.
They catch and bag at the knees, make scratching an itch nearly impossible, rub uncomfortably as we walk and restrict our movements. Nor are shirts really much more practical. They have the insufferable tendency to creep up from beneath the belt and spill over the edge of the trousers. Another drawback to shirts is that, as everyone knows, it is all but impossible for anyone except a highly trained laundress to fold a shirt neatly. Jackets are not so much uncomfortable as they are amusing.
