Beowulf, the Limmerick

It seems Beowulf is popping up everywhere these days. SIFF is showing a new Beowulf movie this year (I've got my tickets - do you?) Jeff published a story in an upcoming Beowulf-related anthology. I thought I'd get in on the act, so here's my Beowulf limmerick, composed in approximately 45 seconds:

There once was a Dane from Herot
Who took Grendel's arms and tore at
They popped off with a twist
And then he made bisque
But Gren's mother did like much like it.
