That is not apocalypse proof underwear sir, that is a towel, I will have to ask you to leave and come back with the right basic equipment for this apocalypse.
While I do recognise their wonderful utility, we are running a tight operation here, we can't simply let someone with only a towel and without the prerequisite equipment outlined in the sign up forms. If you do not have a pair for yourself you can use one of the used pairs around the place, I think we have a anti-apocalypse bra around here, you need not need the parts for the article you simply need it on yourself, as you see I am wearing the anti- apolocalypse bathrobe.
But to fix something, there must be something broken, for something to be broken, it must be in pieces what once was a full thing, but in truth are the broken pieces not full things themselves?
