A friend of mine was having digestive issues. The doctor wanted to do "exploratory surgery". Those two words should never be used together. Think about it, they want to slice you open, then play "21 guesses" to figure out what's wrong! Shouldn't it be the other way around, you know what the problem is, and do the surgery to correct the problem?
Exploratory is fun when you're hiking or with your girlfriend, but not when you're on the operating table.
