A mother was reading a book about animals to her 3 year old daughter.
Mother:
"What does the соw say?"
Child:
"Moo!"
Mother:
"Great! What does the cat say?"
Child:
"Meow."
Mother:
"Oh, you're so smart! What does the frog say?"
And this wide-eyed little 3 year-old looked up at her mother and in her deepest voice replied, "Bud."
