Translation party! Also, Batman!
http://translationparty.com is a web service for translating English phrases into Japanese and back again, over and over again until it reaches “equilibrium.” Feeding it sentences about Batman seems to produce the most hilarious results: http://translationparty.com/#7113686 http://translationparty.com/#7113751 http://translationparty.com/#7113810 http://translationparty.com/#7113838
Of course, this is just a corollary of the general principle that Batman makes everything funny: http://shortpacked.com/d/20050311.html
