Well, my WIFE was some. There's two wooden ones that can be put across the sink (one big, one little), a paddle-shaped wooden one, a smallish plastic one, two or three of the flexible ones, a little wooden one in the camping gear, and part of the kitchen counter is a removable butcher block.

Sometime I just use an ol' stump, though. Works pretty good, you can burn it up when it splits too bad, and it sure as heck saves me from uxorious wrath about the floor.
