S6E19: Lisa's Wedding
I just want you to know I've always been proud of you.
You're my greatest accomplishment, and you did it all yourself.
You helped me understand my own wife better...
and taught me to be a better person.
But you're also my daughter.
I don't think anybody could have had a better daughter than you--
- Dad, you're babbling.
- See? You're still helping me.
