Henry Doodle

I taught Henry to sing the song "Yankee Doodle" except we sing it "Henry Doodle" since that is a nickname that we call him a lot. We've been calling him Henry Doodle, Doodlebug, Henry Doodlebug, etc. for quite a while, so he'll answer to any variation of that nickname. After singing "Henry Doodle" to him two or three times, he had the song memorized. Here he is singing his own version, "Henry Doodlebug":

After he's done, he always says "Good job singer!" I'm not sure what he was doing at the very end...to his end.
