Who Is Mysterion?

While waiting for the bus, it suddenly became clear to Stan, Kyle and Cartman who Mysterion really was.

 

So Innocent

Data: "Tasha, I apologize, but I do not understand your request of me. How does one enjoy engaging in combat while being nude in a tub of Jell-O?"

Getting Older

Picard: "Yes, yes! The Devron System!" (long pause) "Wait, why were we going there again? I tell you, Will, getting old sucks."

I'll Have What She's Having

Seven: "Ensign Kim, I don't know where you believe this lunch date is going, but this will NOT be an instance of 'When Harry Met Seven.'"

Klingon Translation

Spock:  "Commander Uhura, I find it highly illogical that you've been the highest ranking communications officer on the Enterprise for many years, yet you never learned the Klingon language. I could only hope that a parallel universe version of yourself would be more fluent."
