Best Humorous Argument for God

Looks water tight to me: Best Humorous Argument for God:

1.Beers that exist are greater than beers that do not exist, and as such existence is a great-making property.
2. If God exists, God is the greatest conceivable being.
3. Let’s assume the greatest conceivable being does not exist.
4. If (3) than there is something greater than the greatest conceivable being.
5. (4) is a contradiction, so (3) is false.
God exists and we know this because of great beers.
Contrary to Kant, every philosopher I know believes that beers that exist are greater than beers that do not exist. It would be offensive to humanity, the Rolling Stones, and your grandmother to deny Premise 1.
