Megalithic Poems

We need some megalithic limericks.
Limericks! Now yer talkin!

There was an old sarsen from Salisbury... ;-)

There was an Old Sarsen on Salisbury,
That got lost on the road out of Avebury;
Said the Devil to 'e,
It's a posset for me,
Or I'll bury thee deep beneath Silbury.

(The Devil should sound like John Laurie :-)
