“The Mouse and the Hippo,” Friend, Sept. 1992, 27
The Mouse and the Hippo
A mouse and a hippo once built a balloon.
They thought they’d be able to fly to the moon.
The mouse was quite sure it was made of green cheese.
The hippo was certain they’d both of them freeze.
But these facts they’d never be able to prove,
’Cause when they got in, the balloon wouldn’t move.
