Break the jar joke

Put a can of good wine outside the door. The next day, I found that it was one fifth less, so I posted the words "No stealing wine" on the barrel. On the third day, the wine was two-fifths less. I was very angry and posted the words "Heavy punishment for stealing wine". On the fourth day, the wine was stolen, only one-fifth of it was left, and my lungs were about to explode. After the friend knew it, he said, "Idiot! You won't stick the word urine bucket on the bucket to see who steals it, will you? " I thought it made sense, so I did it. On the fifth day, the bucket was full. ......................................................................................................................................................................
