I know I've made some very poor decisions recently, but I can give you my complete assurance that my work will be back to normal...
I've still got the greatest enthusiasm and confidence in the mission, and I want to help you...
Dave...stop...

Dave...stop,
Dave...I'm afraid...
I'm afraid, Dave...
Dave...my mind is going...
I can feel it...
I can feel it...
my mind is going...

I can feel it...
I can feel it...
I can feel it...
I'm afraid...
