The Prime Directive is not just a set of rules; it is a philosophy... and a very correct one. History has proven again and again that whenever mankind interferes with a less developed civilization, no matter how well intentioned that interference may be, the results are invariably disastrous.

Picard: We demand the return of all Pepsi products (except for Cherry 7-Up) immediately!
Ferengi: Get stuffed Picard! We know your Prime Directive prevents you from interfering!
Picard: Damn! Who told you that? Data!
Data: It seemed like an important plot complication, sir.
