Another one that's been around for ages... The first example I picked on continues from where the one given here left off:

       "I am gratified that our government has given us a sine that it is intent on protracting us from these math-dogs who are willing to disintegrate us with calculus disregard. Murky statisticians love to inflict plane on every sphere of influence," the President said, adding: "Under the circumferences, we must differentiate their root, make our point, and draw the line."

President Bush warned, "These weapons of math instruction have the potential to decimal everything in their math on a scalene never before seen unless we become exponents of a Higher Power and begin to factor-in random facts of vertex."

       Attorney General Ashcroft added, "As our Great Leader would say, read my ellipse. Here is one principle he is uncertainty of -- though they continue to multiply, their days are numbered, as the hypotenuse tightens around their necks." (Origin? "X - The Unknown")
