RIKER: Computer, release command control to this station. Authorization, Riker-Omega-Three. Okay, Morta. The Enterprise computer system is controlled by three primary main processing cores cross linked with a redundant melacortz ramistat and fourteen kiloquad interface modules. The core elements are based on FTL nanoprocessor units arranged into twenty-five bilateral kelilactirals with twenty of those units being slaved to the central heisenfram terminal…..you do know what a bilateral kelilactiral is, don't you?
MORTA: ….Of course I do, human. I am not stupid!
RIKER: …No, of course not. Now this is the isopalavial interface which controls the main firomactal drive unit. Don't touch that! You'll blow up the entire firomactal drive!
MORTA: What? Wait….What is... what is a firomactal? Just explain it to me!
RIKER: Sigh! That is the firomactal drive unit...it controls the central ramistat core and also keeps the ontarian manifold within forty thousand KRG.
