What would you do to entertain your family w/o spending any money?

I can entertain my family without spending any money by watching movies in the house together.
After watching movies in the house together, I will cook them a delicious food and we'll eat together. In this little things that i'm doing, I know that my parents will appreciate it and will be glad on what i'm doing. I think that's the best way to entertain my parents.
