For those of you who aren't familiar with Japan, you often find signs like these at nicer baths.
Literal translation(for the 'funny' effect): "People with tattoos, very drunk persons, and gang members may cause an inconvenience to the other customers and shall be refused entry."
Traditional organized crime in Japan is called the yakuza. They often have full back tattoos that easily set them apart from the rest of society. You can also pinpoint them if they are missing joints of their pinky finger.
Although Jude may seem "very drunk," I can promise you he isn't. ; )
