Doctor Arridor

"What are we going to do?"

"What a Ferengi always does in a situation this grave."

"Panic?"

"No, you idiot! He goes to the Rules of Acquisition. Unabridged and fully annotated with all 47 commentaries, all 900 major and minor judgments, all 10,000 considered opinions. There's a rule for every conceivable situation."

"I told you there was no rule."

"Then it's time to invoke the unwritten rule."

"The unwritten rule?"

"When no appropriate rule applies… make one up."

"That's a very good rule."

"Arridor?"

"What is it now?"

"We had seven years of pure profit."

"We did, didn't we?"
