When Abe and Craig start fighting, Lois' position changes between shots, from next to Polly to next to Hal.
When the family arrives at the baseball convention. Lois is speaking, during that same sentence a guy in the background wearing a light blue buttoned up long sleeve and blue "LA" dodger hat keeps showing up on different sides of the family. First the left then the right, his hat is forward then his hat is backwards then in the distance his hat is forward again. Then his shirt is completely unbuttoned.
