Who can tell me the joke that pigs are refined?

One day. Xiao Hehe came home from school and saw a pig seller on the roadside. I bought one and went home. Xiao Hehe feeds it with his own food and milk every day. After a while, one day. Xiao Hehe was sleeping late when he heard someone wake him up. Hehe got up and found no one. He said to himself, who called me just now? I only heard a dull voice in the corner: of course it's me. Little sweet pig It turned out that the pig spoke. = = 1L is so funny \ (o)/~
