The Special Ed. bus driver is wearing a surgical mask. Those kids must be toxic.
One of the posters in the back of the classroom read "Our Pets" and one of the pictures was of an alien.SOUTH PARK GENETIC ENGINEERING RANCH
Pip is directly from Charles Dickens' Great Expectations - Philip Pirrip. He quotes from the first paragraph of the book, much as Cartman quoted from Thoreau's Walden in his winning Save Our Planet essay. Pip must have been expecting a fabulous lunch! It seems like he chose the first dish below.

The windows on the first floor of the Marsh house change in size several times in the episode. When Shelley throws Stan out the window the windows are very wide. This is also the case when Mutant Stan is taken to meet Shelley.
In the middle of the episode Shelley throws Stan around again. She throws him across the room and he lands on dry carpet. She walks over to him, and he's in a puddle of water. No explanation is offered as to how the puddle got there, but after some research, there is an explanation after all: There was a segment in there after Shelley walks over to Stan where she lights a match and throws it at him to light him up. Then she douses him with water a few times in regret and a puddle forms underneath him. When Comedy Central got the episode to air they asked Trey and Matt to take this piece out, because there have been real-life cases of children actually trying to set other kids on fire with lit matches. Mike Judge got in trouble over portraying this on Beavis and Butt-head, and CC didn't want that kind of trouble. Apparently, though, other nations DO get the original version, with Shelley setting Stan on fire and all.
One of the kids at table has an "Elway" lunch box. Both are Hasidic. Beyond them, on the wall below the clock, is a poster of an alien with the caption, "Have you seen me". The first kid says, "This fish is just hurting my anus", and the second one answers, "Naw, it's pretty fresh"
Terrence's henchboys are the same two that taunt Stan about his dog in Big Gay Al's Big Gay Boat Ride, but the shorter one's voice deepens here.
Pig and Elephant DNA Just Won't Splice - a fictitious song attributed to a not-so-famous group. Who bothered to check?

The part where Terrence yells "Daddy, Nooooooooo!" when his dad shoots the genetic clone of Stan, comes from The Omen. It's the next to last scene when Gregory Peck is in the church and is going to stab Damien.
Stan's father sure looks a lot like the geologist from Volcano - same haircut and mustache, pocket protector and attire - so one can assume that Stan's father is the town geologist.
