A Shoggoth on the roof
Sounds crazy - no, certifiably insane!
But here in our little village of Arkham, Massachusetts, you might say every one of us has a Shoggoth on the roof
And I'm not speaking of metaphorically!
It's not easy having a... malevolent shapeless monster like that, hanging over your head, but there it is!
Arkham is the home of many strange things
A big monster like that on such a pointy roof
You may ask: How does it stay up there, if it's so difficult?
That, I can tell you in one word: Tentacles!

where's the cat?????

Looks like this might be based on that blurry photo of Lovecraft attempting to smile.
