HAHA! I remember when I was in school the math teacher (7th grade maybe) insisted we memorize Pi to 12 places. I asked why.

"Because I told you to."

"But where will I use it?"

"Don't worry about that. Just memorize it."

"There are two chances of that happening: slim and none. And Slim is out of town for a while."

I was sent to the principal's office, expecting a butt warming. Instead, I got a lecture on how this taught discipline. I asked the principal if he knew Pi to 12 places. His face got red and he finally sputtered, "Damn it, Steve, just do it, okay!?"

The teacher bitched to my mother (who drove a school bus for the school district). Her reply was, "What bullshit! Totally useless information."

No, I never learned it to 12 places.

Pi = 3.14

And that may be,
All I need,
To know.
