Visible crew/equipment: Before the start of the last basketball game, when Ned calls out, "Jane!" for the third time in the shot facing him as he tries to pass someone, the actors' green T-mark and three other tape marks - one yellow and two red - are visible on the floor ahead of Ned. (Visible on DVD fullscreen.)
Visible crew/equipment: When Mike satiates his hunger in Ned's kitchen, just after Ned says, "That's your can now, we'll label it like that," the reflection of a crewmember moving around is visible in the cabinet's glass pane, to the left of the screen. In the other shots of the same angle we don't see movement, so we know it's not Mike's reflection.
