Explanation
The comic shows a little girl storming away from her father, declaring "You. People. Are. Disgusting." The father, holding a book, asks the mother "What was that about?" The mother explains that she was tired and accidentally read the "Where Do Babies Come From" picture book to their daughter backward.
The punchline reveals the hilarious consequence: read in reverse, the story of human reproduction becomes a tale where "the mommy eats a baby with her vagina and then she and daddy celebrate with sex." The father awkwardly goes along with this interpretation. The humor comes from the absurdity of a children's educational book becoming something grotesque and nonsensical when its narrative sequence is simply reversed, and the parents' embarrassed inability to correct the misunderstanding gracefully.
