I've seen those also! their funny. but not really sure if it's comparable.. you can't reenact being kicked in the ribs 20 times then really hard right to your bladder. lol

I seen a video like that, they have a thing where they stick onto there stomach so they can feel labor pains, another one so they can feel baby move and kick, and I seen on Buzzfeed the try guys wearing a suit that acts like a women's body when they're pregnant.
