This is a quote from memory from one of my professors in grad school:

Last quarble, the shanklefaxes ulugled the flurxurs. The flurxurs needed ulugled because they were mofoxiliating, which caused amaliaxas in the hurble-flurble. The shakletfaxes domonoxed a wokuflok who ulugles flurxurs, because wokuflok nuxioses less than iliox nuxioses.

1. When did the shaklefaxes ulugle the flurxurs?
2. Why did the shaklefaxes ulugle the flurxurs?
3. Who did they get to ulugle the flurxurs?
4. If you were the shaklefaxes, would you have your ulugled flurxurs? Why or why not?
5. Would you domonox a wokuflok who ulugles flurxurs instead of an iliox? Why or why not?

Notice how if you only memorize things, you can reasonably answer the first three questions but not the last two. But if you actually understand things, you can answer all five. Instead of memorizing things, you will get a lot further in life if you actually understand the reasoning behind them.
