This is a humourous explanation of the undoing of Pascal's Wager. Pascal's Wager implies there's only one god (the one the speaker believes in) and the wager is that it's safer to bet on the god and be wrong than to bet against it and be wrong. So if Christianity is the only religion in the world and every Christian agrees 100% on how the religion works, then the wager makes sense. However, when you realise there are thousands of gods, and a great many of them which have claimed a role in creation, then the wager falls apart.
As for Klingon religion, it's as safe a bet as any of them. I mean who's to say Stovokor isn't real. Okay, it's heavily based on Norse mythology (but way more metal!), but Christianity is based on a bunch of older religions, too. They pretty much all are, the ones people know the names of anyway. I'm not saying it's not fine to believe in one, it's just illogical to judge someone for not believing.
