I don't get it.. Won't we always see some black regardless of viewing angle? The light we can see is what is too far away to "get sucked in"?

Haha. It's a math joke, not a physics joke!

A mathematician and two companions are on a train passing through an agricultural area in Scotland. They see a brown cow out the window. One companion (you can make them a physicist, an economist, whatever) says, "All cows in Scotland are brown." The second companion says, "There is at least one brown cow in Scotland. (That one's a logician, I think). The mathematician says, "There's at least one cow in Scotland with at least one brown side."
Thanks from topsquark and Joppy
