Explanation
This comic features a person praying to God, asking: "Dear God, why did you kill the dinosaurs?"
God responds from the heavens: "They were doing it in the butt. Doing it right in the butt. So I asteroided them."
The person looks uncomfortable. God then reassures him: "Fear not, little one. I have mellowed with age."
In the final panel, the person throws his arms wide and exclaims: "Praise the Lord!"
The joke operates on multiple levels. First, it provides an absurd theological explanation for the asteroid that killed the dinosaurs: God sent it as punishment for anal sex, treating the Cretaceous extinction event as a morality-driven smiting. This parodies the real-world tendency of some religious figures to attribute natural disasters to divine punishment for sexual behavior they disapprove of.
Second, the reassurance "I have mellowed with age" is meant to be comforting -- God is saying he would not asteroid humanity for similar behavior. But the fact that God's idea of "mellowing" is merely graduating from extinction-level punishment to tolerance is darkly funny. It implies that the Old Testament God's wrath was not righteous judgment but more like anger management issues that have improved over billions of years.
Third, the person's enthusiastic "Praise the Lord!" at the end suggests he is just relieved not to be asteroided, rather than disturbed by the revelation that God once committed mass extinction over a sexual preference. The comic satirizes the way believers sometimes accept troubling theological implications as long as they personally are not the target.
