[Flash-forward to Lisa's wedding]
Homer: Little Lisa, Lisa Simpson. You know, I always felt you were the best thing my name ever got attached to. Ever since the time you learned to pin your own diapers, you've been smarter than me.
Lisa: Oh, Dad...
Homer: No, no, let me finish. I just want you to know I've always been proud of you. You're my greatest accomplishment, and you did it all yourself.

Lisa: Dad, you're babbling.
Homer: See? You're still helping me.
