Hippo And The Tiger

The hippo had his mouth wide open. A curious tiger swam over to the hippo to ask why he opened his mouth.

"I am just waiting for a dental appointment," said the hippo.

"Oh, I see. Who is your dentist?" asked the tiger.

"Just wait and watch," said the hippo.

Suddenly, a blue bird flying low landed right inside the hippo's mouth and started cleaning his teeth.
