Why do birds fly south in the winter?
Because it's too far to walk!

What is "out of bounds"?
An exhausted kangaroo!

Have you ever seen a duchess?
Yes - it's the same as an English "s"!

What followed the dinosaur?
It's tail!

Did you hear about the mad scientist who put dynamite in his fridge?
They say it blew his cool!

Would you like a duck egg for tea?
Only if you quack it for me!

I've got a wonder watch. It only cost fifty cents.
Why is it a wonder watch?
Because every time I look at it I wonder if it is still working!
