Corrected entry: When the boys dig up Kyle's dead grandmother, the last name on the tombstone is "Broflovski." But when the cemetery people go to Kyle's house to tell his parents what happened, they tell his mother "your mother" has been dug up. Unless her maiden name is also "Broflovski," which is unlikely, the dead woman would have to be Kyle's father's mother.
Corrected entry: After the episodes "Cartman's mom is a dirty slut" and "Cartman's mom is still a dirty slut," in which we find out that Cartman's mom is actually his father and his mother is yet to be found, Cartman's mom is still always mentioned as Cartman's mom even when the kids say Cartman has no mom, and also they say he has no dad.
Corrected entry: When Satan announces his party, he says that you have to have a wristband and a costume to get in. But when Biggy Smalls shows up at the party, he doesn't have a costume on, even though the party was the same night he appeared in Butters' bathroom.
Corrected entry: When Cartman visits Chris Hanson to call off his appearance on Dateline (he is currently unable to keep from blurting out his unfiltered thoughts), he lies that his grandma died and that he has to go to Memphis. His "Tourette's" then kicks in and he admits that his grandma's fine. His grandma, however, died earlier in "Cartmanland" (season 5 episode 6) and at this point, he knows of only one parent (his mother/father Liane). (00:16:00)
Corrected entry: Tweek's parents tell him that they have installed locks on his window and door so that he is safe from abductors. But if Tweek's door and window are locked at night by his parents (as we see during the first night when they are teaching him not to open the door to anyone but them), then how did Frederick Johnson get into Tweek's room?
Corrected entry: When the seniors take over the town, they put all the adults into a camp so that they can't stop them, but near the end of the episode, the seniors are surprised that Country Kitchen Buffet is not open. They shouldn't be surprised because if all the adults are in a camp, then there would be no one around to open up the restaurant for the seniors.
Corrected entry: While Tay Zonday (Chocolate rain guy) is fighting with Chris Crocker (Leave Britney alone!) he is holding him by the hair and holds his gun to his head. The next wide shot of all the fighting in the room, the gun has disappeared from his hands, but he is still holding Crocker by his hair.
Corrected entry: When Cartman is walking the streets thinking he's died, it's a school day since you see him visit the school swarming with pupils and he is seen waiting with the other boys at the bus stop. But if it's a school day, what's Butters doing at home? And if it's because he's sick, why is he outside shovelling the snow off the driveway?
Corrected entry: At the end when Cartman finds out he's not really dead (everyone was just ignoring him), he storms over to Butters and accuses him of lying to him by telling him he'd died. But earlier on, when Cartman and Butters meet, Cartman's the one who told Butters he had died.
Corrected entry: When Cartman goes to buy North Park Funland, he tells the owner that he is buying the theme park to keep people out so that only he can ride the rides. But wouldn't it have been better if Cartman had just told the owner to only let him enter the park, and given the owner the $1 million in order to pay for the staff and all the necessities like food, maintenance etc?
