Sometimes scientists go too far

And what they do isn’t nice

Like crossing a cat and a parrot

To make a carrot that chases mice

Now scientists down our way

Got my Uncle Jim in a tiz

By crossing an antelope and a lizard

And coming up with my Aunt Liz

There were scientists who found

They had no dessert left to eat

So they crossed a fruit bat and magpie

And their fruit pie went down a treat

They wanted a bird to dance a ballet

So crossed a toucan with a cockatoo

I don’t know if they made a dancer

But at least they’d got a tutu

There was a scientist called Old McDonald

Who took a cow and emu as a pair

And now on his farm in Scotland

He’s got moo-mus everywhere

They are checking the oddest combination

For the first signs of any hairs

Before introducing to the world
