Harold and Kumar go to White Castle - Fast Arm?
In the scene when Harold and Kumar are at the gas station after Neil Patrick Harris steals their car, Harold walks toward the gas station and sees the extreme punks throwing stuff around. It cuts to Kumar as he points behind himself with his thumb and says "There's a pay phone across the street if you don't want to deal with those a$$holes." then he puts his arm down. It then cuts, facing Harold from behind Kumar and Kumar's arm is up again.
