Going to Class Pays Off (Sometimes)

Today in one of my classes, the professor said, "And now we'll see the power of the Heine-Borel Theorem," and I thought, "He just said, 'the power of the heinie.'" And that made me not so angry about being in a boring class.
Once a Chinese professor of mine said, "Why are you freaking the bear?" When I looked up from my notes, though, he'd written on the board, "What about inflation?" And a Japanese professor of mine would say "bid-ask spread" and sound exactly like he was saying "big-ass spread."
Other than those three moments, going to class has usually been a waste of time.
