This is the exact encounter I had with two first graders in the lunchroom last week...
1st Grade Girl: "Ms. Sweeney, he just called me liar, liar, pants on fire!"
1st Grade Boy: "Ugh! Yes, I did. But is it even true that inside our bodies is ham?"
Me: "What did you just say?"
1st Grade Boy: "Do we have ham inside our bodies?"
1st Grade Girl: "Yeah, like if you cut open your arm, inside is ham, right?"
Me: "I will answer you as soon as I get back from laughing my head off."
Yet another instance where it is proven that you can never ever correctly predict what a kid is going to say to you in the lunchroom.
