Naruto Shippūden S11E228 — Fight! Rock Lee!
Overview
Might Guy recalls their "visualization" training with Lee in order to avoid learning the Drunken Fist and forgetting an incident which Might Guy apologizes to the restaurant owner with humiliation. Lee, who is determined to train to be stronger than Naruto, follows Might Guy's orders and resemble animal fighting styles which represent on a restaurant menu. However they failed, until they tried on training on a moving boat. Like Guy who has seasickness, Lee also suffers from seasickness but he uses it to balance the boat which resembles exactly as the Drunken Fist fighting style. Guy lately realizes that Lee is also aware of the restaurant incident and Lee was only protecting Guy from a drunk man which causes the restaurant to be totally damaged.
