Eternal life with a piece of paper on the back of your ass. What's so funny?

It is said that two women played mahjong until after 3 o'clock in the middle of the night and passed a cemetery on their way home. At that time, two women were upset, so it was convenient next to the cemetery. Neither woman had any paper with her. One of them was smart enough to take off his underwear and throw it away. Another woman looked at a wreath beside her, wiped her ass with a piece of paper on the wreath and took her pants home. The next morning, their boyfriends made a joke on the phone, so they heard the man say that my buddy was not good on the phone. I found out that my wife was having an affair and came back at 3 o'clock in the middle of the night last night. When I came back, my shorts were gone. At that moment, another person spoke. Dude, you're okay. Yesterday, when my daughter-in-law came back at three o'clock in the middle of the night, she not only lost her shorts, but also had a piece of paper on her ass that said "Eternal Life".
