This is a send-up on one of the most interesting surviving pieces of Old English poetry, Wulf and Eadwacer. You can learn more about it here.
Ærwulf is on one island, I am on another.
But that does not matter
for he is a helicopter gunship.
It is strong there, ringed by swamps,
Slaughter-fierce men crowd about
But he will tear them apart when he comes into their camp,
for he is a helicopter gunship.
It is not like that with us.
