As may have become apparent over the years, I've long been a fan of HP Lovecraft and always enjoy bringing Lovecraftian humour to light (or is that to dark?) (here, here and here, for example).
I saw this one via Katy Southern on FriendFeed: Selections from H.P. Lovecraft's Brief Tenure as a Whitman's Sampler Copywriter.
They're all funny, here's one of them as a taste (hehe):
Coconut Creme Swirl
They say that the Coconut Creme Swirl sleeps. But if the dread Coconut Creme Swirl slumbers, surely it must also dream. It is certain that while it dozes the Coconut Creme Swirl is absorbed by terrifying visions of exacting its creamy tropical vengeance upon mankind! Consume the Coconut Creme Swirl before it awakens to consume you!
