After Drama is displeased with the assortment of foods Turtle brought back to him on the tray he throws it in the garbage can, causing it to fall. Right after we can see the garbage can standing as Drama turns around.
When Johnny and Turtle are standing by the Lincoln at the end of the shooting day, a girl in a green dress walks past Johnny in the same direction three separate times. However, this episode had a plot involving a sexy dark-haired extra. Because of this and the fact that it is so obvious, it may have been intentional as an inside joke.
