Are there any hilarious jokes?

A man saw a store having a big sale and went in. "What do you want?" "I want to buy dog food." "We have a rule that you must prove that you have a dog." "Where is such a rule?" "This is the case with goods on sale." The man has been grinding with the salesman for a long time, but the salesman still refuses to sell it to him. No way, the man had to go home and bring the dog before buying dog food. A few days later, the man went to this store to buy cat food. "Give me two boxes of cat food." "We have a rule that you must prove that you have a cat." It was the same shop assistant, and the man dawdled with her for a long time and finally had to go home and take the cat to buy cat food. A few days later, the man came to the shop with a big cardboard box with a hole in it and found the salesman. "What can I do for you?" "Just put your hand in and you'll know." The salesman put his hand in: "What is it? Very sticky. " "I want to buy two rolls of toilet paper.
