2009 Halloween Math Class v2

2009 Halloween Math Class v2 is a screamer video uploaded by a YouTube user MDWeathers in Oct 30, 2009.

this video is a remastered or second version of the previous video, it started off on a classroom and a tripod camera which is behind on the projector for a better perspective, a Biola University professor Matthew Weathers shows up and steeping behind the projector screen which makes it look like he was inside of the video frame, because its truly better than the way every professor does it,

After he was inside of the video frame, he started to throw off some erasers, moving the chalkboard, spraying water (which also happen outside the video) to falsely demonstrate that he was inside of it as a joke, in the next part, where he teaches students proving 1 = 2, head turning 360°, after he finished teaching about the main topic, now he tells the students to spot the difference between 2 triangles as well as the pumpkin, However, since its a prank video, There will be no difference, regardless of what difference do you see will be resulted as nothing,

While the professor is still waiting for the students to notice the difference between these 2 identical pictures, after around 12 seconds during the puzzle, a picture of Amy Peterson is shown zooming in and out accoumpanied by a loud roar which is the same scream used from Zoeken but its 2x louder than the original due to volume adjust on the video presentation was extremely higher (even if its over 35% or more), ending with a text stating "Happy Halloween!" slideshow followed by with his students' applause, He then follows by throwing the candies to the students before ending the class.
