The idea of a branding our currency with religious endorsements is antiquated, but Lil B is only 23.
God clearly isn't real, whereas The Based God has been seen in Berkley as recently as just the other day.
Even if God were real it seems unwise to officially advocate putting any trust in it, given its well-documented unpredictable behavior. On the other hand, it seems prudent to give thanks to Lil B The Based God, if only for putting out 18 mixtapes so far this year. It's also worth noting that Lil B has never asked anyone to murder their own child or purposely flooded the whole world.
In our culture the tetragrammaton is fast being replaced by the quadragrammaton (#TYBG), and it's time our currency reflected that.
