Psychiatry students were in their Emotional Extremes class. 

"Let's set some parameters," the professor said. "What's the opposite of joy?" he asked one student. 

"Sadness," he replied.

"The opposite of depression?" he asked another student. 

"Elation," he replied. 

"The opposite of woe?" the professor asked a young woman from Texas. 

The Texan replied, "Sir, I believe that would be giddyup."
