Conner: Yeah! I've been a huge fan my whole life!
Milo: I hear they're introducing a whole bunch of new characters, new Jedi's, a young Anakin Skywalker, and they introduced his mother Shmi (pronounced shmee)
Conner: Naw bro, her name is shimmy
Milo: I just looked at the book that we sell here and its spelled S H M I and phonetically it sounds out shmee

Conner: Incorrect! No bro, it was episode II, 2002, AND it was you who thought it was shimmy!
