Hole in my bum!

My daughter was about two yrs old and had just gotten out of the bath. I carried her out to the livingroom in a big towel and sat her on the couch. While I was back in the bathroom to clean up, she had unwrapped and was cruising around in the buff. When I came back to the front room she had her hand on her bum with a horrified look on her face. I asked her "What's the matter baby?" and she replies, "Mommy! There's a hole in my bum and I just put my pinger in it!!"
