Brown Bear, Brown Bear, what do you see?

Our school’s protocol for bear visitors.

Introduces the Solar System to students. Puts up picture of planets in order from the Sun. Only read the first three planets aloud to the students.
Student A: "Uranus!" Hoard of Students: *snickers* Uranus! *laughter* Uranus! Teacher: Could you explain why that is so funny? Students: *dead silence* Teacher: Okay, then we're done laughing at names of things.
Class heads into hallway and Teacher debates stopping students to have them explain why "Uranus" is funny to a coworker. Teacher can't keep a straight face just thinking about bringing it up to another adult. Lets moment pass.
