Twenty-One

There was a teacher at my school (she retired a couple years ago) that referred to her birthday as the day she turns 21 each year. Well she was explaining to her 3rd grade class that it was her birthday and she was 21 (she was really in her 60's) and a student said, "no you're not!" To this she framed her face with her hands and replied "doesn't this look like the face of a 21 year old to you?" Without skipping a beat the 3rd grader responded "well yes, but that neck is way too old and wrinkly!"
