I always wanted a picture of one of these things, but between the trains movement and a keitai's fickle nature, I never could get it ledgible. These signs crop up in our trains in Japan. I find them extremely humorous; a true example of how some things don't translate quite right. See them all at Contibento, Jeff somehow got really good pics of them all.
For another funny pic, see the zombie blog. (site pimped: check).
