it's my life

A mother was reading a book about animals to her 3 year old son:
Mother: "What does the cow say?"
Little Johnny: "Moooo!"
Mother: "Great! What does the cat say?"
Little Johnny: "Meow."
Mother: "Oh, you're so smart! What does the frog say?"
The wide-eyed little Johnny looked up at his mother and replied, "Bud."
