My economics professor is hilarious. The other night he was lecturing and talked about doubling the inputs to a production process. He started to write "DOUBLE" on the board and was talking. He wrote "DO" then turned around to say something. When he went back to the board, he wrote "BLE". Then he looked at what he wrote, "DOBLE", confused. That look that says, "something is wrong, but I'm not sure what".
Someone commented that this was Spanish for DOUBLE. He asked "Really?". They assured him that they were serious. He turned back to the board and said "Well, I'm bi-lingual and didn't even know it."
Later he commented about two economic terms, the short-run and the long-run. He wrote them on the board and asked the class the difference. Everyone was quiet (sometimes when he asks questions, he wants an answer, sometimes not). After a moment of silence, he commented well, in the long run, we're all dead so it really doesn't matter.
Class is always interesting....
