3. Apocalyse Now - the episode where Elaine went to Burma and Peterman said "Are you an assasin?"
4. Last of the Mohicans - the episode where Kramer was lost in the East Village and Jerry said "Stay alive! I will find you!"
5. Marathon Man - the episode where Kramer pretended to be robbing George in front of the Russian tourists and the old jewish woman was pointing the finger at him.
