A wide-mouthed frog went to the zoo to see what the other animals feed their offspring.
"Mrs. Elephant," said the wide-mouthed frog, "What do you feed your babies?"
"I feed them elephant milk," said the elephant.
"Oh, that's nice." (<--- in the wide-mouthed enunciation.)
She walked on to the hippopotamus. Mrs. Hippopotamus, what do you feed your babies?"
"I feed them hippopotamus milk."
"Oh, that's nice."
Next, she encountered the lion. "Mrs. Lion, what do you feed your babies?"
"I feed them wide-mouthed frogs."
(Scrunching your mouth up as tight as possible --->) "Oh, that's nice."
