Continuity mistake: When Bob and Handy are talking beside the Moose at the start of the film, they are talking about Handy's nose. Right after Handy says that when Bruce (The Moose) is there, his nose looks normal. As he says this, Bob looks down. Then as the camera changes angle to look at Bob for the reply, he is once again looking directly at Handy.
Continuity mistake: As we see Handy fixing the toilet in the President's house, he is holding a wrench in his right hand. Then after he bumps his head, he tries to get up and then grabs the wrench with his left hand. However, once the camera angle changes to show him getting up the wrench is back in his right hand.
Continuity mistake: As the camera pans over the Presidents home we see the president arriving in an escorted car. From the view above we can see a man mowing the lawn, moving from right to left across the camera. Yet, when the shot changes to a low level shot of the car pulling up the drive the man mowing the grass is nowhere in sight.
Continuity mistake: During the scene at the end of the President's date with Sally when the two are talking on the porch, two cameras were used in the scene. The one that's on Sally is shot on a rainy night and the one on the President was shot on a clear night.
Continuity mistake: As Handy leaves the President's house at the start of the film we see Plunger his dog having sex with the Presidents dog. As he calls the dog over we see him pick the dog up by his front legs to talk to him. The buckle on the dogs collar changes position from the front to the side when the camera angle switches from facing the dogs face, to the shot from behind it.
