Who can tell me some interesting stories and jokes?

1. A pig ran forward, ran and ran, hit the wall and ran back; I ran to the original place, ran forward and ran, but hit the wall again ... I walked back and forth several times and hit the wall every time. What's the problem? (Answer: Because pigs can't make sharp turns)

2. One day, you had a contest with a dog, who won? Result 1: You win (congratulations, you are smarter than the dog) Result 2: You are tied (it turns out that you have the same IQ as the dog) Result 3: You lose to the dog (your IQ is worse than the dog).

3. Is the English word for pig "P-I-G" or "P-U-G"? Most people will answer the first one and then ask: u (you in homophonic English), and the answer is generally: I (I in homophonic English).

4. What animal likes to ask why? Answer: pig (most people will ask why, and then he is a pig)
