The eyes of the "dead body" at the beginning of the episode were rapidly moving under the actor's eyelids, which were twitching.
Jake's friend from high school pronounces Tokyo correctly as To-kyo despite supposedly knowing little about Japan and the language. If that were so, he would mispronounce it as Toh-kee-oh as most people unfamiliar with the language do, especially in the late 1990s in which this story is set. Clearly, the actor is more familiar with Japanese than the character is supposed to be.
