Come on! There is a joke about Tang Priest's master and apprentice parachuting. Does anyone know?

It is said that four priests Tang and the little girl were all on the gray plane. The gray plane crashed, but there were only four parachute bags. Taoist Tang stood up and said: I can't die until I finish the important task of learning from the scriptures. I want to be original. Then he jumped with an umbrella bag on his back. The Monkey King said that I wanted to protect Master from death, so he jumped down with an umbrella bag. Pig Bajie sighed: Affection has been pity and hate since ancient times, and this worry is endless. Old pig, Huilan and I are waiting for me in Gaolaozhuang, and Brother Pig still needs me. I ... I ... I went there, and then ... after that, it jumped into the umbrella bag, too. But Friar Sand was surprised to find that there were two umbrella bags. He shouted, "God never shuts one door but he opens another. We won't die." . Bless Buddha. But soon found restless, such as Buddha Guanyin, Jesus, didn't God play mahjong? How come? So I asked the little girl why she had an umbrella bag (women are cautious, you know). I saw the little girl naively say: Uncle Pig, um ... from my ... schoolbag on my back.
