Other: When Tom Hanks is walking down the stairs a chainsaw comes through the wall. If you look at the wall a second earlier you can see a line where the chainsaw is supposed to come through.

Continuity: When Art is eating breakfast at the Peterson's house, he takes items from the fridge. Watch when he comes back over and talks to Ray. The position of the pineapple under his arm changes from shot to shot.

Revealing: After Art & Ray successfully blow up the Klopeks house, Ray emerges from the ruins and the porch collapses behind him. It can be seen that the porch supports are dragged backwards towards the house to allow the porch to collapse behind Ray.

Continuity: The position of the femur in Ray's dog's mouth is different in subsequent shots.

Continuity: After everyone leaves from visiting the Klopecks, the guys are talking back at Ray's house. Ray says that he found Walter's wig after the dog came up from the basement. But in that scene, you can see Ray tucking the wig into his shorts before the dog even appears.

Continuity: When Hanz takes the lid off the garbage can, he puts it down with the handle up. Before he gets back to can with Stomper, the lid is down, but he picks it up without turning it over.

Continuity: This makes the second time that this mistake - discussed earlier - occurs. After Klopeck's house blows up, Carol Peterson drives back into the neighborhood to notice all the commotion. The first camera shot (shown from inside the vehicle) shows the front passenger's head rest to the seat is missing. Next camera shot (shown from the outside of the vehicle) shows the head rest as being back on the passenger's seat.

Continuity: At the Klopecks, the bonfire of 'romantic' candles changes with each shot, from big candles to severely melted ones back to full ones again, a few times throughout the scene.

Continuity: In the scene where Tom Hanks' wife is in her station wagon to leave, look at the neck pads on her seat. In one shot, they are missing, but in the next shot, they appear.

Continuity: When Ray and Art are running away from the Klopek's house due to them being chased by bees, in the distance you can see Walter's house. He runs into his house about 3 or 4 times between shots.
