I was just marvelling at the progress mankind has made in just the past century or so, and I wondered what y'all thought the greatest invention ever
has been.As much as I adore air conditioning in the hot,humid Carolina summers I think I'm gonna have to go with the ....roll of toilet paper!So
let's have it, what do you think is the all time greatest invention?
