Star Trek: The Next Generation1987

[final scene of the play 'Frame of Mind', with Riker as the patient and Data as the doctor]

Lt. Commander Data:
Perhaps we should continue this discussion next week.

Commander William T. Riker:
No. I wanna talk about this now!

Lt. Commander Data:
You're starting to sound angry again. Maybe you need another treatment.

Commander William T. Riker:
What I need is to get out of this cell! I've been locked up in here for days. You've controlled my every move, you told me what to eat, what to think, what to say. And when I show a glimmer of independent thought, you strap me down, inject me with drugs and call it a 'treatment'.

Lt. Commander Data:
You're becoming agitated.

Commander William T. Riker:
You bet I'm agitated! I may be surrounded by insanity, but I am not insane. And nothing you or anyone else can say will change that. And I won't let you or anyone else tell me that I am. You may be able to destroy my mind; but you can't change the fact that I'm innocent. I didn't kill that man!

Commander William T. Riker:
[smirking madly] And that's what's driving *you* crazy.

Lt. Commander Data:
I can see we have a lot of work to do.

[exits]

Commander William T. Riker:
[shouts after him] Nothing you can say will change the fact that I'm innocent! I'm not crazy! I'm not crazy... I'm not crazy...
