Colorado boy

So, Ian comes home with a worksheet for the letter D. He plops down with his crayons and says:
"Da da da dog.. dog starts with D"
"Da da da door... door starts with D"
"fe fe feather.. that is not D"
"Da da da doll.. doll starts with D"
and so on.
Then I hear:
"Eh eh elk. That is not a D!"

Me: "Honey, I think that is supposed to be a deer."

"Oh!"
