Next verse:

Me: "Old Mcdonald had a farm! Eee-i-eeei-i-oh! And on that farm he had a...."

Peyton: "Dog transformer!"

Me: "Ee-i-ee-i-oh! With a woof woof her and a woof woof there, here a woof there a woof, everywhere a woof woof. Old Mcdonald had a farm ee-i-ee-i-oh! And on that farm he had a...."

Peyton: "Horse transformer with a gun!"

Me: "Ee-i-ee-i-oh! With a nay nay boom! And a nay nay boom! Here a nay, there a boom, everywhere a nay boom! Old Mcdonald had a farm ee-i-ee-i-oh! And on that farm he had a...."

Peyton: "Cow transformer with a really really big gun!"
