How about you and me get together for a nice friendly
game of poker.

I'll bring the cards.  I'll bring several decks, so we can
use a fresh deck for each hand.  This saves time, because
they're already shuffled, using my favorite PRNG.  The PRNG
is strong enough to make it computationally infeasible for
you to find any non-random pattern in the cards.
