Philip [to Marge]: Oh! Remember Woodstock?
Philip: Twenty of us tried to squeeze into that tent. Vivian and I jumped into that lake naked!
Vivian: I wasn't at Woodstock.
Philip: Oh yeah...
[Marge shows an album of old photos to the family]
Hilary: Oh my god! Who are those two weirdos? And who is that ugly little kid in the dashiki diaper?
Vivian: Well, those two weirdos are your father and I, and that ugly little kid is you.
Carlton: The bone in your hair is a good look for you, Hilary.
Will: Yeah, you've got sort of a... yabba-dabba-doo.
Ashley: Mom! Look at how short your skirt is!
Philip: Ohh, your mother's legs made the mini-skirt famous!
Ashley: I have mom's legs. Can I wear my skirt that short?
Philip: You have MY legs and the answer is 'no'.
Philip: Geoffrey will take your bags up to the guest room.
Marge: I carry MY OWN bag.
[To Geoffrey] My brother! You have been oppressed, repressed and suppressed by capitalism! Don't you know you can be free?
Geoffrey: I have known freedom - Don't like the health plan.
Ashley: Greetings, Sister Adesimbo! Greetings, Brother Olufemi! Power to the people!
Will: Oh, Ash... You kinda look like... Winnie the Pooh Mandela.
Ashley: Mom, daddy, I am a depressed minority, and I want my allowance increased.
Ashley: Then I'm staging a sit-in and I won't eat my peas.
Philip: You WILL eat your peas.
Ashley: Come on, daddy! Suppose Gandhi's parents treated him like this!
Philip: Gandhi ate his peas.
Ashley: Then I shall spray paint my demands on the pool house wall.
Will: Hey look, fellas! There ain't no point in tryin' to reason with the Man when the Man is not tryin' to reason wit' you!
Kellogg: Right on!
Will: What we gotta do is get up in his grill and show him that we got the power!
Kellogg: Yes! Power to the people! Say it loud - I'm black and I'm proud!
Will: Ohh, aight. My man Cornflake got the spirit... He a little confused, but he got the spirit...
Marge: Looks like I've had quite an impact on your kids!
Philip: You're proud of getting a highschool kid suspended?
Marge: If you mean, am I proud to have told him to do anything you have to for what you believe in, then yes, I am.
Vivian: Marge, when you talk to Will about when we chained ourselves together at sit-ins, you're only giving him the romantic part of the struggle. Girlfriend, you are leaving out everything that went before it! The leaflets, the petitions, the years of trying to work through the system!
Marge: The system doesn't work! You HAVE to blow the door down! Looks like you forgot that!
Philip: You talk as if I wasn't there with you in Birmingham facing dogs and firehoses. This is me - Olufemi! The same Olufemi that was with you the night Harlem went up in flames! But now I have a family and I CHOOSE not to fight in the streets! I have an office to fight from, and I have fought and won cases for fair housing, affirmative action, health care, and I am not ashamed to write a big fat cheque for something I believe in, and that doesn't make me any less committed than you, so don't you DARE look down your DAMN nose at me, Adebola!
Marge: You know, when I was your age there weren't many doors open to us. Some of them we HAD to blow open, and because we did, you've got more opportunities. Hey, don't get me wrong, I'm not saying that things are perfect, it's just that now you can fight our battles in the boardrooms too, and in the classrooms, the voting booths, and the courtroom just like your uncle.
Will: Alright hold up, hold up. I thought you said "By any means necessary"?
Marge: Right! But it's up to you to figure out what's necessary. And Will, when the courtroom doesn't work... Come find me.
Will: You're a deep sister, Adebola.
Marge: And you... are the future, Hasani.
