The pig was amused by the joke.

When I was a child, my class organized to go to the countryside to study farmer uncle farming! There is a big open pit beside the ground. The surface of the cesspit was covered with a hard shell by the sun ... a classmate in our class poked it with a small stick, which was quite strong! So I shouted "Fly on water" and rushed up ... I transferred after I came back ... I know you smiled.
