L.B.O.E.
A brain that doesn’t fit in a box. It’s like a kid who doesn’t know what subject they are in and just answers questions randomly.
My brother is an L. B. O. E. He thinks math is just counting and spelling is just yelling.
My teacher called me an L. B. O. E. because I answered the science question with a joke about pizza.
My dog is an L. B. O. E. He thinks the mailman is his best friend and barks at the TV like it’s a rival.
