Silly

O RLY?

Prove to me you're self-aware. Prove I'm not a brain in a jar and that you - and my keyboard - aren't figments of my imagination.

(PROTIP: It's impossible - or, if it isn't, several centuries of philosophy have failed to do it.)

How do you prove anything? with logic and understanding. I think therefore I am. simple.

Cogito ergo sum. Main problem with that is it's quite a leap from 'I think' to 'I exist'. Also, I see little evidence of thinking here.
