My mom and dad are here for the weekend babysitting my nephew. It’s Mom’s turn to entertain the baby:

“Old McDonald had a farm E I E I O. And on that farm he had a cow E I E I O. With a moo moo here and a moo moo there, here a moo, there a moo, everywhere a moo moo. Old McDonald had a farm E I E I O.”

(Deep breath.)

“Old McDonald….(long pause)….had another cow.”
