Ashton Kutcher: More public changing tables!

New dad Ashton Kutcher has a new cause: baby changing tables.

In public men's rooms.

The Two and a Half Men star, who with fiancee Mila Kunis welcomed daughter Wyatt five months ago, put out a simple call to action a few days ago on his Facebook page — and it's resonating.

"There are NEVER diaper changing stations in men's public restrooms," he complained.

"The first public men's room that I go into that has one gets a free shout out on my FB page! ‪#‎BeTheChange‬," he continued in the post.

Meanwhile, fans have offered many suggestions.

Among them: the state of Virginia, any Walmart store, the Spinnaker Beach Club in Panama City Beach, Fla., the Dubai Mall, New Zealand and the Music Pier in Ocean City, N.J.
