English Original
A little boy walks into his parents' room and sees his mom on top of his dad, bouncing up and down.
The mom sees her son and quickly dismounts, worried about what he has seen. She dresses quickly and goes to find him.
The son sees his mom and asks, "What were you and Dad doing?"
The mother replies, "Well, you know your dad has a big tummy, and sometimes I have to get on top of it to help flatten it."
"You're wasting your time," says the boy.
"Why is that?" asks his mom, puzzled.
"Well, when you go shopping, the lady next door comes over, gets on her knees, and blows it right back up."

妈妈回答：“嗯，你知道爸爸有个大肚子，有时我得趴在上面帮他把它压平。”
“你在浪费时间，”男孩说。
“为什么这么说？”他妈妈困惑地问。
“嗯，你去购物的时候，隔壁的阿姨就会过来，跪在地上，把它又吹大了。”
