What's the funniest/ most embarrassing memory of yourself that you've never told anyone else?

I broke my nose with a shopping cart! That was a little embarrassing. There were a bunch of people standing around watching me bleed all over the parking lot. It was at the hardware store, there was a bucket of drywall mud in the front of the cart. I pushed the cart over the curb and front went down, the back went up and the handle caught me right under the nose. Blood everywhere, hurt like hell, felt like an idiot!!
