DNA Nursery Rhyme

Mary had a little lamb,
its fleece was slightly grey,
It didn't have a father,
just some borrowed DNA.

It sort of had a mother,
though the ovum was on loan,
It was not so much a lambkin,
as a little lamby clone.

And soon it had a fellow clone,
and soon it had some more.
They followed her to school one day,
all cramming through the door.

It made the children laugh and sing,
the teachers found it droll,
There were too many lamby clones,
for Mary to control.

No other could control the sheep,
since their programs didn't vary,
So the scientists resolved it all,
by simply cloning Mary.

But now they feel quite sheepish,
those scientists unwary,
One problem solved, but what to do,
with Mary, Mary, Mary...
