There was once a wide mouth frog. She had babies but didn't know what to feed them.
She went to the cow, talking with her mouth real wide, she said, "Cow, what do you feed your babies?"
The cow said, "I feed my babies milk."
The frog went on to the horse and, talking with her mouth real wide, she said, "Horse what do you feed your babies?"
The horse said, "I feed my babies hay."
Finally, the frog came to a snake, talking with her mouth real wide, she said, "Snake what do you feed your babies?
The snake said, "I feed my babies wide mouth frogs."
The frog said, with her mouth really small, "Oh, is that so?"
