What is yellow and never stops talking?
Who hides his last name under a train?
What color is a hippopotenuse?
What does a walrus do in the rain?
What did the granny say to the lion?
Where do elephants go to sneeze?
Why did the fishmonger write a sonnet?
If it’s a Tuesday in April, who hid the cheese?
Can Earth revolve yet make no motion?
What did the chicken sing to the sky?
Knock, knock. Come in, if you’ve a notion
and tell me specifically: how does time fly?
