Gluteus Maximus

Tonight my daughters picked Dr. Seuss's Sleep Book as their bedtime story. In the book there is a part that reads,"some on their stomachs, and some on their fannies." I asked my 5 year old daughter if she knew what a fanny was. She looked at me and said,"Uh, No." I explained it was her butt and she sassily said, "Actually Mom, you're wrong, thats my Gluteus Maximus." I was laughing so hard I just said your right.
