Letter to the North Pole

My second grade students wrote letters to Santa today. After they asked for what they wanted, I instructed them to say something nice to Santa. One of my young students forgot this all-important last step in the body of his letter. He then brought It to me for editing.

Me: Dude, you forgot to say something nice to Santa.

Boy: [confused look on his face]

Me: You have to say some thing nice to him.

Boy: How about, "You're not fat; its your stretchy pants"?
