Since Sheryl Crow thinks we should only use one square of toilet paper for conservation purposes as well as use a "dining sleeve" instead of a napkin, I have a suggestion for her:

She can eat her used toilet paper.  It's natural recycling!  And as creepy skinny as she is, it'll probably be filling, too!  And, if she's still hungry, I'm sure there are fans that'd be more than happy to send theirs to her as well.

Think it'll work?
