Useless Information thread

Just for a bit of fun and some light hearted relief from the more sombre threads on here,I thought that it might be fun to post any oddball or off the wall bits of information that are totally useless.

This morning while in the bathroom and doing the "necessary paperwork"Man LOL I looked inside the cardboard core of the paper roll and found that the use by date was stamped inside.

Now:

1. Why does loo paper need a use by date

2. Who in their right mind in the supermarket will juggle a large packet of paper rolls to ensure that they all have the same and current date inside them.
