Well, now it's possible, in a way. The new Grinderman merchandise, available on grinderman.com, includes tea towels with the faces of Mr. Cave and his partners in crime printed on them. So whether you loved or hated the new Grinderman record now there's a brilliant opportunity out there to express your feelings by buying one and using it the way you find most appropriate.
Personally, I think tea towels are the most useful piece of merchandise I've seen in a long time and perfect for such a whimsical band. Actually, I wouldn't mind getting one for Christmas. Could use one in my kitchenette.
