Shredder: This is Baxter Stockman? Huh. You've lost weight.
Stockman: Of course it's me! Look around you! Do you think this facility would have been possible without my genius? These imbeciles working for you have the technological savvy of amoeba!
Shredder: And you've been very naughty, Stockman; betraying me once too often. You should have quit while you were...a head.

I float and I think
And I think and I think
About walking or driving a car
Or riding a bike
And I think and I float
Because I'm just a brain in a jar
"Brain and brain — what is brain?!"

"I am still here. I can see nothing, feel nothing. You have locked me into hell for eternity. If this is all there is, I would rather die now... Trapped like this, like a sponge beneath the sea! Yet even a sponge has more life than I. Can you understand a thousandth of my agony? I, Morbius, who once led the High Council of the Time Lords, and dreamed the greatest dreams in history! Now reduced to this, to the condition where I envy a vegetable!"
