Teachers always need to learn

While eating lunch with some of my boys, one of them asked me what I was eating.

Me: "It's a pumpernickel sandwich"
Student: "Isn't it called plumpernick?"
Me: "No, Pumpernickel, Haven't you watched Barney, It's his favorite sandwich."
Student: "Miss Welch. We are in second grade. We are way to old for that show, but it's okay, I know your a teacher, and teachers need to learn things."
