So What's the Problem?
We don't know about you, but there have definitely been times when one sheet of toilet paper just isn't enough. And that's every time.
"I'm clearly not familiar with standard pooping."
Crow helpfully suggests that we can use two or three sheets for when that rare, exceptional shit calls for it. Now, without getting too graphic here, let's just say that after a night out involving a case of beer and a heap of heavily-spiced Indian food, two or three sheets would be nothing more than a preliminary damage assessment.
Crow later tried to pretend she had meant it all as a joke, but this was probably after she realized everyone was sitting on the opposite side of the tour bus from her.
Look how uncomfortable Sheryl Crow's butt makes John Mayer.
It Could Have Been Worse...
Crow could have taken her war against paper wastage to above anal levels and suggested making clothing with built-in napkins on the sleeves. Oh wait, she already did.
