AP Calculus Teacher-"Heh Heh Heh. I can't wait to see the look on every student's face since I threw in several Calculus II and III problems.
Final Exam Day
Senior Student- "Phew. I pulled off 3 all nighters for this piece of sh*t Final I'm about to take." *Looks at Final* "WTF?! My teacher never taught me this!"
*AP Teacher looks at student and laughs in his head* "Muhahahaha!!!"
Uber-nerd: "Wow, partial differential equations are fascinating. With some minor modifications, I bet these formulas could even predict the stock market..."
"I got a 56!"
"Way to go!" (insert high five here)
Senior Math major: "Bitch, please. I'll take related rates and integration by parts over rings and external direct products any day."
