My Mom tells me stories about Sears & Roebuck catalogs (she is 68, you probably have went through that eh PB?) and used up corn cobs.

I've honestly had to use pine straw before while hunting and have used newspaper at work before. Down here working in the middle of nowhere (which isn't hard) there are not any bathrooms and the boss wasn't going to let us rack a truck up and drive 10-15 minutes OR MORE to the store and use theirs. Just grab some shit and go. After one time I started stocking my truck with toilet paper.
