His primary purpose in life is to praise every decision George Lucas ever made - which, I have to believe, could be confusing for Lucas. For example:
1997
"Rick, I'm thinking of adding Ian's scream from Jedi to Mark when he falls away from Vader in Empire."
"Oh, George, that's sensational! Wow! You've done it again! I'm glad this state of the art technology allows you, only now, to fulfill your Original Vision (TM)."
2004
"Rick, remember that scream we added to Luke in Empire? I'm considering removing it."
"Amazing! Sir, your intellect and judgment are boundless! I'm so glad we, at long last, have the means to bring to the screen your Original Vision (TM)!"
