Before her wedding, Homer had given her a very soulful conversation as a luckiest dad.
Homer: Little Lisa, Lisa Simpsons. I always felt you are the best thing my name ever got attach to. Since you learnt 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. 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've had a better daughter...
Lisa: Dad, you're babbling.
Homer: See? You're still helping me.
Well, my father has taught me a lot of things. One of them is "Big boy must not cry" but this episode really prove him wrong, even I have watched it several times.
I've always said that "Lisa's Wedding" is my favorite Simpsons episode ever, but I think "Holidays of Future Passed" is an equally good one. And this moment here, yes, it's just adorable. It shows how Homer, despite all of his clumsiness, truly loves and cares about Lisa, and Lisa, despite knowing how different they are, truly loves her father and rest of the family, too.
Father-and-Daughter love forever!
That was a great episode!
