The commercial was first based upon the expression, "Does a bear s...t in the woods"? I don't know how they are wiping, but the aim must be wrong as the pieces are all over the kid's behind. They have evidently invaded grandma's house and killed both Little Red Riding Hood and the wolf as well. The boy bear doesn't wear pants but there is a big concern that if he was able to wipe his behind with Charmin, vs any other toilet paper, he wouldn't leave streaks and the underwear wouldn't have to be washed. One would certainly conclude that rather than Charmin being the product to buy, that the male species is unable to wipe their behind correctly!
You would not know all of this unless you are stuck watching this commercial.
