One thing that used to alternatingly amuse and annoy me was the way some of my students (and even teachers) would mis-translate one of my favorite book and movie series, The Lord of the Rings. As we all know, "l" and "r" can be problematic for Japanese, and the katakana form of this particular title don't really help matters. As a result, sometimes people would tell me that they liked "The Road of the Ring."
Now that I think about it, that title isn't too ridiculous given the story. The main characters do indeed travel a long road...of the ring.
