I would never consider wearing long johns after eating at Long John's. That's just one more layer that has to be removed before experiencing the same effect as that pre-colonoscopy stuff they make you drink to clean you out.
why don't you carry a M2 50 cal with you all the time? because its not practical, so you compromise on your suppressive fire and light armor piercing capability for more concealable means. so I guess that means you have no principles also?
