WASHINGTON, April 24 (UPI) -- Singer and environmental activist Sheryl Crow wants the American people to think about conservation, even about everyday things such as toilet paper.
Turns out her comments about limiting how much TP could be used at one sitting was a stab at humor, she said on her blog on the Huffington Post.
"And by the way guys, the toilet paper thing ... it was a JOKE!!" Crow wrote.
Earlier, Crow posted, "I propose a limitation be put on how many squares of toilet paper can be used in any one sitting."
Crow's conservation note came as she was wrapping up a U.S. tour, traveling in a biodiesel-powered bus promoting efforts to curb global warming, the Times of London reported Tuesday. It also came just a couple of days after her run-in with Republican political strategist Karl Rove, who reportedly snapped "Don't touch me!" when she touched his arm as she tried to talk to him.
Laurie David, who produced Al Gore's environmental documentary "An Inconvenient Truth," was with Crow at the time.
"I've never had anyone be so rude," David said of Rove's behavior.
Rove said David "came over to insult me and she succeeded."
