Xiaoming's jokes are very complete and hilarious. Which one is your joke?

Xiaoming's uncle was ill, and Xiaoming felt very sad, so he wrote a letter to his uncle. The letter said: Dear uncle, uncle can't write, draw a circle. I heard that you are sick and can't write. Draw a circle. Please protect your body. Your body can't write. Draw a circle. Please don't get out of bed again. The bed can't write. Draw a circle. Your nephew can't write. A few days later, his uncle received the letter. His uncle was embarrassed and couldn't help reading: Dear Big Egg, I heard that you laid eggs. Please protect your eggs. Please don't lay any more eggs, your nephew Xiao Dan.
