Fat Tuesday Misconception

Yesterday, my first grade class had a conversation about the fact that today would be "Fat Tuesday." Mr. Nelson, the host teacher, didn't go into much detail about the what that meant, but told the class we'd be talking more about it today. So this morning while the kids were unpacking their belongings, Neil runs up to me, frantic. "Mrs. Miller, Mrs. Miller! I forgot my Fat Albert costume at home!" At 7:45am, you can imagine I was stumped. "What? What are you talking about?" I replied. "Well, Mr. Nelson said that today was 'Fat Tuesday.' I'm not fat...so I figured if I wore my Fat Albert costume, that would be ok, and I could just pretend to be fat. But I left it at home!"

My first though: Oh boy...where to begin. :)
