George the Infinite

George was a pirate, but he wasn’t a very good pirate.
Still, he did what he could, and at the beginning of the day he’d stand in front of the mirror and give himself two thumbs up.
The mirror-George would give him two-thumbs up back.
George then mounted a mirror on the opposite wall so there’d be an infinite number of him giving himself an infinite number of thumbs up.
Curious about the nature of infinity, he pulled books by Cantor and Dedekind from his bookshelf while his crewmates yelled for George to bring up more ammo, God damn it.
