I think every line in Almost Famous espouses rock and roll to the fullest degree (that would be 11), but there are some that pop out like saggy boobs at a Journey show.
Jason Lee: That is the FUCKING BUZZ!
Billy Crudup: And you can tell Rolling Stone that my last words were.... I'm on drugs!
(again) Billy Crudup: Woo! Peggy Sue, Peggy Sue, pretty pretty Peggy Sue!
Patrick Fugit: I love you. And I'm about to boldly go where... many men have gone before.
Billy Crudup: Hey, hey. You know that Marvin Gaye song, "What's Happenin', Brother?"
Patrick Fugit: Yeah, yeah!
Billy Crudup: You know that one "woo" he gives, right after the second verse?
Patrick Fugit: I know that woo! ... woooo!
Billy Crudup: Yeah, man, that's it! That's what rock and roll is, man... it's not the stuff you put in, it's the stuff you leave out!
Kate Hudson: How old are you?
Patrick Fugit: I'm eighteen.
Kate Hudson: Me too!
Patrick Fugit: I'm... seventeen.
Kate Hudson: Me too.
Patrick Fugit: I'm really sixteen.
Kate Hudson: ... Me too. Isn't it so much better to have the truth out --
Patrick Fugit: I'm fifteen.
And if I could honestly remember anything but the last line, the Bowie fan's little group of lines ending with "OH MY GOD IT'S BOWIE!"
