How to write a joke when dad tells it?

After dinner today, our family sat on the sofa and had a rest together. My mother said to me, "Let's tell jokes." . My father and I said "Yes" in unison.

Dad told a joke first: a rich man gave a farmer a note that said,' Bring the cow to my house at noon'. The farmer can't read, but he pretends to say "OK, I'll come to your house right away" in front of the rich. After the joke, my mother and I couldn't help laughing.

Later, my mother went on to say, "Spiders have eight legs. One day it accidentally fell from the tree. How many legs do you think it has left? " I quickly replied, "It's still eight." Mom smiled and said, "Wrong, wrong, there are seven left, because it still has one leg patting its chest and saying;" God, you scared me to death. Dad and I both laughed before I finished.

Finally, it was my turn to say, "A dog proposed to the bear, but the bear refused, saying," I won't marry you because I don't want to have a bear. I want to marry a cat, so the panda born is very precious. "My parents laughed at the jokes I told, and I felt very happy to hear my parents' happy laughter. I hope mom and dad will always laugh and be happy.
