Corrected entry: When Peter has the fight with the chicken in the part where they are on the overpass and the chicken lands on the truck then, the truck is driving away from the overpass but Peter doesn't move in the next shot it shows Peter on the same overpass but the truck the chicken was riding on again drives under the same overpass Peter is on with the chicken on the same truck.
Corrected entry: Right after the Y2k takes effect and it shows the family (assumed to be only a little while later), Peter comments on how he was the third Hardy Boy. When Lois corrects him by saying that there were only two Hardy Boys, Peter says "Just like there was no apocalypse? HE SHOOTS HE SCORES." and slams into Lois with his stomach, causing her to fall down. When the shot changes, Louis is suddenly back on her feet. The transition between the two was less than a second - not nearly enough time for her to get back up.
