My useless bit of knowledge for today

[Paul Sandhu]

When you see a semi loaded with porta potties unloading at an industry or some other place where there can be an event or gathering, it means there are going to be lots and lots of people coming in the near future.  You can also replace the words porta potties with golf carts in that last sentence.  The people may need a place to stay.

What's your useless bit of knowledge?

If you are ever constipated, I know a delicious salad bar that will clear you out in less than an hour.

Every. Single. Time.
