Try not so hard, and remember the power of understatement.
If you blatantly state the improbable, go on as if nothing had happened, then act surprised when people react to your characters as if they are ,godlike?
A lot of variations on the hook, you just need to snag their interest. and with a story this short you aren't asking for a major commitment of time.
and it's a 12 pound sledge, not one of those wussy wooden mole mallets, but no problems for the nimble at heart.
