this one made me laugh out loud... not sure the moms i know would love it, but I know the kids would!!!

As we all know, we all “go,” and that, of course, includes zoo animals! Dung is also integral to the design of our kids’ “Ele-Poo” T-shirts, which are adorned with a wrap-around depiction of an elephant. On the front, you’ll find the cartoon profile of an elephant’s face and side, and on the back, the backside, complete with a comical representation of what comes out of it. When it comes to getting the scoop on poop, we’ve got it!
