What are some good jokes that would work as deflections for when my family harasses me about when I’ll graduate?

I’m about to visit a lot of family, and know every person and their mom is going to ask me this. The truth is I’m a very bad student and also don’t like taking a full course load. I like to enjoy life. I also just gave birth to twins, and I love my current job. They won’t care. I just want enough jokes so that I can deflect and make them laugh and we can talk about something else. So far I have for “when will you graduate?” “when I finish all my classes.” “At the right time.” Not bad but not my best, I think the stress is clouding my comedic abilities. Can anyone help me with some good funny responses?
