What does earthworm play football by laparotomy mean?

There is a joke that earthworms can cut themselves into two pieces to play table tennis when they are bored, and they can cut themselves into two pieces to play football in 22 minutes ... Of course, this joke is false, because earthworms don't have such strong regenerative ability. When you are really bored and want to find someone to accompany you, it is definitely a worm that can do this!

The regeneration ability of duckweed is almost infinite, no matter how many parts are cut, new ones can grow. A scientist named Morgan once cut the worm into 279 pieces, and each piece can grow into a complete worm, which can form about 10 football team, a cheerleading team and several melon eaters.
