BOB DYLAN'S ROCKIN OUT!
Whoa. Don't worry about my math teacher, he is the coolest I've had yet. He's happily married, has an adult child, I don't think he is a threat...
But don't worry about me or my math teacher.

What dx Actually Means
You remember talking about Dx (delta x) in a precalculus course. It represents a distance along the x-axis; or, to put it another way, the difference between any two values of x. Well, dx means exactly the same thing, with one key difference: it is a differential distance, which is a fancy way of saying very, very, very small. In technical terms, dx is what happens to Dx in the limit when Dx approaches zero.
Now, when you have a quantity whose value is virtually zero, there's not much you can do with it. 2+dx is pretty much, well, 2. Or to take another example, 2/dx blows up to infinity. Not much fun there, right?
But there are two circumstances under which terms involving dx can yield a finite number. One is when you divide two differentials; for instance, 2dx/dx=2, and dy/dx can be just about anything. Since the top and the bottom are both close to zero, the quotient can be some reasonable number. The other case is when you add up an almost infinite number of differentials: which is kind of like an almost infinite number of atoms, each of which has an almost zero size, adding up to a basketball. In both of these cases, differentials can wind up giving you a number greater than zero and less than infinity: an actually interesting number. As you may have guessed, those two cases describe the derivative and the integral, respectively. So let's talk a bit more about those, one at a time.

In much simpler terms dx is the rate of change in x

Actually, I thought of a better version of the joke:
The functions are bullying all the other maths around. e to the power of x goes scaring the lil' deltas, sigmas and pis. Says one d: "You leave me alone or you'll regret it - I'm dy!"
(whatever you do to e to the power of x, there will almost always be the function itself in the resulting term. But differentiating for a different variable makes it go 0
)

I was thinking the same thing. I'm in 10th grade, and we when over that last week.

Here is the version of Lt. Killer's joke that I remember:
An exponential function and a constant function were out walking, when the constant function suddenly spots a differential operator.
-- Look out, we have to hide, says the constant function.
-- Why? says the exponential function.
-- It that differential operator gets hold of me, he will differentiate me, and I will vanish.
-- Coward. I am the exponential function. No differential operator can harm me, says the exponential function, and walks toward the differential operator.
-- Hello, I am e^x, says the exponential function to the differential operator.
-- Nice to meet you, smiles the differential operator. I am d/dy.

Heh, I'm giving away my "geek" side by admitting that I understood that and laughed my tail off.
One of my physics professors had some horrible physics jokes - I wish I could remember a few of them.

I knew some programming jokes, but can't remember them now.
Just one:
Did you know... 31 oct = 25 dec ?

Oh lord, the worst chem/physics joke ever, my physics teacher really does suck with jokes lol...
Two hydrogen atoms were talking in a bar...
H1: I think I've lost an electron.
H2: No way, are you sure?
H1: I'm positive!!
