How much poop does the average person have in them at any given time.?

I would like to know both pounds and inches.,How much poop does the average person have in them at any given time.?
I hope that you didn't lose any sleep last night thinking up this dumb question.
I know how you can find out. The next time you feel like you have to go, bring a ruler and a scale with you and measure the length and mass of your poop. Ask friends, neighbors, and your friendly neighborhood grocer to do the same. When all the numbers come in, get the average!!
