Irony on a T-Shirt

A couple of weeks ago (actually the day before Hope and Bud's wedding!!!), we were sitting in a FF restaurant when we observed some high school kids selling coupon books to raise money for some education-related cause. They all wore T-shirts imprinted with a slogan along the lines of "Education - We Support It's Cause" - with the apostrophe in the word "it's." So we support "it is cause" - so much for education.
