A Perfect Stool
whose trajectory upon exit carries it down the plumbing and completely out of view, leaving no evidence (on T.P. or in bowl) that a stool was ever present. Acknowledged as an act of divine intervention.
So, I'm on the shitter and I go to wipe - nothing! Completely clean! Then, to my amazement, I peer into the bowl and there's nothing there. Immaculate stool! Praise the Lord! It's as though Jesus reached down from Heaven and anointed my anus with the holy spirit!
