Harry Potter and the Chamber of Mudbloods Alternate Scene

I went Flea Market shopping this past weekend, and while I was shopping, I found a DVD of Harry Potter and the Chamber of Secrets. As a big fan of the Harry Potter series, having loved the books, movies, etc. I got giddy. I noticed the cover was different than the usual. Actually, it was a bit odd: Harry's glasses looked to be snapped in half, looking shocked, while Ron and Hermione were staring at him, looking as if they were trying not to laugh. There was a random Dobby tossed in the bottom center, clearly not meant to be there. At the time, I thought nothing of it, so I went ahead and bought it. All of my memories of watching this movie came over me, so I could not wait to get home and check it out.
So I get home, and pop the movie in, and it is pretty much as I remember...until The Weasleys fly Harry out of Number Four Privet Drive. They ended up dragging Uncle Vernon across the sky for about ten minutes, as he proceeds to scream in his usual Vernon fashion. It appears their car malfunctioned, as it just kept flying in circles, rising high and low. It lasted for a while, and then Vernon fell down. Very odd, I didn't know they filmed more of this scene, having seen deleted scenes from this film before.
But nevertheless, the rest of the film seemed to go on as normal, which changed once it got to Gilderoy Lockhart's class. There was this strange added in scene, in place of the Pixies causing mayhem, with Gilderoy Lockhart's wand going berserk, as it started bouncing and bopping all over the place, and he ended up in his position like he were somehow using his wand as a pogo stick. Hermione's spell (immobulus?) that she uses in the regular version got used here to freeze the pixies, but got Lockhart as well, who ended up stuck in mid-air, shaking in place as if he were on an invisible paint shaker. He asked for everyone to stop it, but the scene cut away here.
So the next one is where it gets really wild. It's the one that REALLY stands out to me, so brace yourselves...
It's the Mudblood scene, where Draco first mentions about Mudbloods. So it starts out almost the same, until Draco mentions "My father can afford the best." Hermione and Draco started getting into an aggressive and verbal assault match. Their insults were way more intense, and went on longer. Suddenly, they start getting into a rap battle against each other, with Ron beatboxing for Hermione, and Flint beatboxing for Draco (which sounded terrible due to his teeth). Their raps then upgraded into Insult Scat, as the beatboxing stopped. After that, they got louder and louder, and then the whole verbal battle degraded into just long, drawn out screaming, with the camera switching back and forth between Hermione and Draco. What was really crazy about this, even for what was going on, was the fact that neither of the two ever stopped to even take a breath. It just kept going and going, until their screams got loud and distorted. The camera would, however, sometimes show the reactions of the other students, such as Ron looking unnerved, Seamus Finnegan laughing, or Harry looking confused. Collin was taking pictures, of course, grinning like the little rascal he is.
So after all of that, Draco went on a long, hateful tangent (saying stuff I can't repeat here), which ended by him calling Hermione a Mudblood. It then cut to Hermione already looking halfway through crying like a small baby. The students gasped in this strange, overdramatic (and repetitive) editing technique where we would see each student stop and turn their head towards the screen, one by one. And then...I kid you not...it kept going until it landed on Pro Wrestler, Booker T...Yes, you read that right, Booker T was in this cut. Instead of gasping, however, he simply stared at the screen and said "Tell me you didn't just say that!" "I believe I did, you dirty bloke." Draco replied. Booker freaked out, and grabbed Ron's arm, who pulled out his wand just as he did so, and pointed it at Draco.
"What spell would you use at a time like this?" asked Booker.
"Eat Slugs?" Ron replied. The spell then went off, and would have hit Booker, but, I guess since Booker's a muggle, it went through him, and hit Ron, electrocuting him, which caused his hair to stand up, his face to turn gray, and his robes to char and smoke, until he slowly fell on his back.
Booker proceeded to freak out, ask if Ron was okay, and then do, what I would only refer to as a Panic Spinarooni. After that, Herry and Hermione went to go check up on Ron, as he ended up projectile vomiting his slugs into Seamus' face. (it always found a way to bend reality just to hit his face for whatever reason) The trio then went to Hagrid's, as the camera held on Booker doing his break dance. Collin kept snapping photos of him.
After that, the movie was entirely the same, aside from an unfinished Deathday Party scene that looked unedited.
So yeah, I have no clue as to what I watched, but whatever it was, it was a trip.
