It's a filler episode, but one of the more enjoyable ones. It isn't very important so you can skip it, but I suggest not to. It's funny how the fake Lee and Gai look nothing like the real Gai and Lee and yet Naruto does not see this. It's another one of those episodes that make Naruto seem extremely stupid. It reminds me of episode 101, where they try to take off Kakashi's mask because It's purely a humor episode. After a series of filler episodes that focus on fighting, it's a nice break to see an episode that isn't serious. Definately worth watching.
