There's a store in San Francisco's Chinatown that sells gigantic wooden phallic symbols (apparently, they're religious icons). I don't know what's more intriguing: the size of some of these, or the price of the bigger ones. For reference, the sheet of paper on which "Religious Icon" is written is a standard 8.5x11.
On a really obscure note: at a quick glance, doesn't one of these larger ones look a bit like the back of Darth Vader's helmet?
