Dr. Chan vs. Dr. Madu/Rap Meanings

Dr. Madu:
'''OK Chan, let's go. I've got an AP class to teach. Time for me to unleash'''

(Dr. Madu teaches AP Biology. He is telling Dr. Chan that, if they are to battle, they must hurry up so he can return to his class.)

I'm gonna spear you with my raps, roast yours like I did my goat Beef Jerky

(Dr. Madu threatens to spear Dr. Chan and roast, or diss, his raps. Beef Jerky was the name of a goat owned by Madu that he allegedly cooked.)

'''Pay attention, don't mis-remember this. Your contentions will get you suspended'''

("Mis-remember" is a phrase often used by Dr. Chan. During his only year at White Station, Chan was suspended for several weeks in the second semester.)

Your mind is splendid, but I better mention that you cannot leave your class unattended

(Dr. Chan is a brilliant mathematical theorist. His mid-year suspension was the unforunate result of Chan leaving his class unattended to retrieve students who had been called to the office.)

Unlike my homeland of Nigeria, my rhymes are cold through and through

(Dr. Madu is originally from Nigeria, and he is saying that, unlike the climate there, his raps are ice cold.)

You only made a layup in that basketball game 'cause they lowered the goal for you

(Dr. Chan participated in a student vs. teacher basketball game at a pep rally and only scored one basket, which many say was because the goal was slightly lowered.)

You're a has-been mathematician with half as much talent as Mr. Foster

(Dr. Madu says that Dr. Chan, despite his background in advanced mathematics, is no longer relevant, and that he is not as talented as Mr. Foster, who would appear in a future battle.)

'''You'd better roll outta here with your Corolla. Trust me, I'm a doctor'''

(Dr. Chan drove a Toyota Corolla. "Trust me, I'm a doctor" is a phrase used in commercials for Dr. Pepper.)

Dr. Chan:
<p class="MsoNormal" style="line-height:16.5pt">Oh OK, now I see who they’ve put me up against

<p class="MsoNormal" style="line-height:16.5pt">(Dr. Chan acknowledges that Madu is his opponent.)

<p class="MsoNormal" style="line-height:16.5pt">You better be sorry that you have decided to cross the Chan Man

<p class="MsoNormal" style="line-height:16.5pt">(Dr. Chan tells Dr. Madu that Madu should regret attempting to battle him.)

<p class="MsoNormal" style="line-height:16.5pt">You need to repent for your sins; the way you teach is very bad

<p class="MsoNormal" style="line-height:16.5pt">(Dr. Chan is Christian and has been said to reference repentance on multiple occasions in front of his classes. He is also attacking Madu's teaching style.)

<p class="MsoNormal" style="line-height:16.5pt">So take out your graphing calculator 'cause we’re about to do some math

<p class="MsoNormal" style="line-height:16.5pt">As you can see, this plot shows the linear decay of your flows

<p class="MsoNormal" style="line-height:16.5pt">(Linear decay is a type of mathematical regression involving a negative data correlation. Chan says that, according to his graph, Madu's raps have declined in quality.)

<p class="MsoNormal" style="line-height:16.5pt">'''Put that away. Show some respect! Be sure and tell your friends: No cell phones!'''

<p class="MsoNormal" style="line-height:16.5pt">(Dr. Chan often gave speeches to his classes about respect. He was also known for a zero tolerance policy regarding cell phones.)

<p class="MsoNormal" style="line-height:16.5pt">Plus, these two axes stretch to infinity in both directions

<p class="MsoNormal" style="line-height:16.5pt">(Axes are a type of guide line used on graphs to demonstrate direction of a mathematical expression's graphical representation. In the case of the graph Chan is referring to, both axes stretch infinitely.)

<p class="MsoNormal" style="line-height:16.5pt">'''Because my brilliance has no limits! I mean, just look at the interval notation'''

<p class="MsoNormal" style="line-height:16.5pt">(Limits are a type of restraint put on certain mathematical expressions. Dr. Chan says his brilliance is unlimited and thus infinite, as evidenced by the interval notation seen in the video.)

Dr. Madu:
<p class="MsoNormal" style="line-height:16.5pt">Tsz Ho Chan no you didn’t, don't think you could ever beat me

<p class="MsoNormal" style="line-height:16.5pt">(Tzo Ho Chan is Dr. Chan's full name and rhymes with the word "no", as in "oh no you didn't." Madu tells Chan that he should not believe he could defeat Madu.)

<p class="MsoNormal" style="line-height:16.5pt">‘Cause you’re just a nutty professor, and I’m a connoisseur of biology

<p class="MsoNormal" style="line-height:16.5pt">(Dr. Madu calls Dr. Chan "a nutty professor", a reference to the Eddy Murphy film, and says that he himself is a pro at biology.')

<p class="MsoNormal" style="line-height:16.5pt">'''Half your students aren't even passing your class. Don't you see what's wrong?'''

<p class="MsoNormal" style="line-height:16.5pt">(At many points during the school year, half of Dr. Chan's students had F's in his class.)

<p class="MsoNormal" style="line-height:16.5pt">Why don't you just pack up your bags and head back to Hong Kong?

<p class="MsoNormal" style="line-height:16.5pt">(Dr. Chan is originally from Hong Kong.)

Dr. Chan:
<p class="MsoNormal" style="line-height:16.5pt">I’m going to make a horizontal shift into a parallel universe where you're having success

<p class="MsoNormal" style="line-height:16.5pt">(Dr. Chan says that he will make a horizontal shift, a term used to describe the movement of mathematical plots along the x axis on a graph, into a parallel universe where Madu's lines are better.)

<p class="MsoNormal" style="line-height:16.5pt">Make sure you write this down, Madu, 'cause it's gonna be on the test!

<p class="MsoNormal" style="line-height:16.5pt">Your rhymes are weak, son, mine are sick to the third power

<p class="MsoNormal" style="line-height:16.5pt">If you ever need a lesson in rapping, come by my tutoring hour!

<p class="MsoNormal" style="line-height:16.5pt">(Dr. Chan offered a tutoring hour to his students during his year at White Station.)
