They give way to those awkward post-teen years where you constantly forget if you're wearing any or not. You can never tell, but everyone else can.
From the kludger:
This is what happens when Marines get sent to the backwoods of Japan with no cable just in time for the Superbowl. That's an AFN dish on the roof of the barracks being aimed and supported with a 20-lb curl bar, 550 cord, and copious quantities of duct tape. FORTUNATELY for all the football fans in my unit, I came prepared with the necessary multittools, compass, duct tape, and 550 cord to make that thing actually get decent reception.
