I Have No Mouth, and I Must Scream (video game)/Fridge

Fridge Brilliance

 * Ted and Benny's tortures are designed to exploit their sense of self. Benny is being deliberately dehumanized, changed into an ape-like creature and being kept in a cage; walking (or at least, standing) upright is the only truly human thing he can still do, so if he sits or lies down, he's basically admitting defeat. Ted's a narcissist, so it doesn't matter if he sits down or not, he can't help looking at himself.
