"Well, guys, it seems that I am the first one of us to reach manhood after all." — Cartman has been trying to reach manhood for quite some time now. First, he thinks he reaches puberty when he confuses a rash that makes blood show up in the stool with a period, which only girls can get. Then he thinks he reaches puberty when he makes friends with a man, but he learns some men want more than friendship with a boy. He remembers that lesson when "Bill Cosby" wants to be his friend. Now he thinks he reaches puberty when he buys pubic hair and pastes it on his crotch. But this time he realizes quickly that he's been cheated. Also, didn't Stan beat him to actual puberty when he took those hormones in "Are You There, God? It's Me, Jesus" (facial hair, boobs, etc.)?
Kyle remembers Scott being in the ninth grade in the beginning of the episode, but in eighth grade when Cartman reveals his plot to get back at Scott to the class. This was corrected on Saturday: he's an eighth grader both times.
"Hey, you wouldn't happen to be Eric Karp-man, would you?" - people have told me the teen boy says Karp-man, not Cart-man, so I had to check out the sound. Yep, he does say Karpman. Matt and Trey have revealed that they based Cartman's last name on a childhood friend of theirs: Matt Karpman.
A Braveheart moment — "You may take our pride, but you'll naver take my Goddamned sixteen dollars and twelve cents"
When Cartman is over at Scott's house, in the background you see two bushes and two houses, and neither bush is at screen center. This remains the case until Cartman and Jimbo go hunting for weaknesses. Then, the bush at screen left moves to center for Cartman. The next day, it's back at screen left. Also, the trees appear only during the day
One of the kids in the crowd in Downtown South Park has a head shot of Scuzzlebutt on his shirt.
That evil grin we saw last month? It was indeed for the first episode! Not the first one aired, but the first one numbered!
Cartman's gathering the other kids in his basement and telling them about his plan to get rid of Scott Tenorman is based on Pew Wee's speech to an uninterested crowd about the theft of his bike in Pee Wee's Big Adventure.
You'd think Stan and Kyle wouldn't come to meet Cartman anywhere after they had laughed at him so hard some nights before, but they do.
"My name is Eric Cartman. I'm a young, supple eight-year-old boy from South Park, Colorado." — Wait, isn't he in 4th grade with the others? Aren't they nine yet? And isn't Cartman even older, like 10?
When Cartman and Scott were trading money and pubes, Cartman thought he was cheated once again, but if you follow the money, Scott gave back the $6.12 Cartman gave him, and so Cartman had no basis in saying Scott took any more money from him.
How could Scott's parents be unaware of Mr. Denkins' No Trespassers policy?
Why didn't Scott wonder why his parents didn't return home the night before the chili cook-off? Why didn't Barbrady reach him with the news?
The music playing at the carnival is the same one from "Damien."
When Cartman and Scott sit down to eat chili together, Butters, Kyle, Stan and Scott's friends stand behind Scott. They're all missing when Scott learns the name of Cartman's chili, and they all reappear after Cartman finishes taunting Scott.
In Cartman's first flashback, where he tells Mr. Denkins that violent pony killers were in the area, the silo next to the barn is missing.
Shakespeare's Titus Andronicus is the inspiration for Cartman feeding Scott's parents to Scott. In the play, Titus gets revenge on Empress Tamora by killing and cooking her sons Chiron and Demetrius and serving them for dinner, for their raping Lavinia (Bassianus' wife) and cutting off her hands and tongue, and killing her husband Bassianus (Emperor Saturninus brother, and so Tamora's brother in law). Alas, Titus did not survive, as he was killed shortly after revealing the contents of the meal. The play also comes in handy when Jimbo and Cartman are on the hunt for info on Scott's weakness: it's during a hunt that Bassianus is killed and Lavinia raped.
