Shortly after Larry and Bill Buckner enter the apartment for the minyan, they are both seen from the front receiving yarmulkes. When the shot cuts to the next and they are shown from the side, Buckner's arms clearly switch positions and he receives the yarmulke again (the same shot was used from different angles but the dialogue continues as normal).
After Larry gets distracted and loses his team the softball game, a woman played by Amy Schumer walks by him and says "what a douche." About five seconds later, the same woman walks the same exact stretch coming from the same original direction and yells "stupid ass."
When the hysterical lady in the apartment that was on fire threw her baby to Bill Buckner, after he caught him the mother appeared right after and Buckner gave the baby to her to hug. Why didn't they just both walk down to the ground floor and out of the building.
