Grampa: All right, son, I'll sell this dump and write you a check.
Homer: Dad, first you gave me life, now you've given me a home for my
family, I'd be honored if you came to live with us.
Grampa: Thank you!
Bart: [in the present] So how long before you shipped Grampa off to
the old-folks home?
Homer: About three weeks.
