In the part of The Wedding Singer where Adam Sandler is laying in the trash can out back, Drew Barrymore comes out to tell him everyone's gone. When we first see him, there's a wire or cord of some sort laying over his right arm. Then the camera switches over to Barrymore. And then once it's back on Sandler, the cord is over on his left arm. Then, after they show Barrymore again, it's back on his right!
