What is the humor about too many express deliveries?

As follows:

1. Time tells me that no one has to wait except express delivery.

2. The express arrived suddenly like a spring breeze overnight.

3. As long as you receive the express delivery, you will feel satisfied! Have a great day today! From morning to night! After waiting for a long time, it finally arrived.

4. I received the express delivery early in the morning. It was so fast and Xiaochao was so cute.

5. When I received the express delivery text message, I was happier than finding my boyfriend, because the boyfriend may not be mine, but the express delivery must be.

6. I already regretted the money I spent last night when I woke up today. The next step may be to receive the express delivery with a soft rhythm.
