Three Little Pigskins
The gangsters, who are trying to enter the room where
The Three Stooges
are hiding, clearly push the door open a couple of times. However, on the Stooges' side, the door does not open at all.
When the stooges huddle, Moe is standing in the wide shot, on his knees in the close-up cut, and standing again in the next cut.
Boom mic visible
Near the beginning, when we first see
, he falls in next to a passing pedestrian to ask for "a dime for a hamburger". The shadow of the boom mic following them can be seen on the sidewalk.
