After watching a Magic School Bus episode about reptiles this afternoon:
Student: Mrs. Butler? I have a joke for you. What do you call it if your lizard has a broken tail?
Me: I don't know...tell me.
Student: A reptile dysfunction.
Me: (sweating) Um, I don't get it...what makes that funny?
Student: I don't know. My mom's boyfriend knows a lot of lizard jokes. He loves lizards!
Me: Well super! (was checking for the sheepish grin, but happily there wasn't one!)
Maybe he'll come back in a few years and explain it to me!
