Roger McGough - Goodbat Nightman

God bless all policemen
and fighters of crime,
May thieves go to jail
for a very long time.

They've had a hard day
helping clean up the town,
Now they hang from the mantelpiece
both upside down.

A glass of warm blood
and then straight up the stairs,
Batman and Robin
are saying their prayers.

* * *

They've locked all the doors
and they've put out the bat,
Put on their batjamas
(They like doing that)

They've filled their batwater-bottles
made their batbeds,
With two springy battresses
for sleepy batheads.

They're closing red eyes
and they're counting black sheep,
Batman and Robin
are falling asleep.
