Not so much best lines, but funniest to me: Apollo yelling at Rocky not once but twice, one time in the boxing ring while they are sparing, and when they are racing on the beach. Apollo yelling, "WHAT THE HELL IS WRONG WITH YOU!?" is hilarious.
Rocky to Mickey right before his fight with the Hulk: Rocky-"What do you think he eats for dinner?" Mickey-"You." While Rocky is getting an extremely harsh beating from the Hulk, his son ask Adrien, "Is daddy having fun?" She replies "yes." So much funny banter in this movie.
'He's hookin', he's hookin', he's hookin'....damn, Rock, come on, what's the matter with you?!?!'....--- those were some pretty good hooks by Apollo....
'To all my love slaves out there...it's Thunderlips, in the flesh bey-beh...the ultimate male versus the ultimate meatball...'
'Lights out meatball!'
'I'm champion of the world!...ugh!...ugh!....ugh!'
'He's hookin', he's hookin', he's hookin'....damn, Rock, come on, what's the matter with you?!?!'....--- those were some pretty good hooks by Apollo....
It's funny because Clubber Lang never jabs when he fights, he throws hooks.
The best is always the first time Creed meets Lang.
"Don't need no has been messing in my corner. And you better get that bad look off your face before I knock it off. You wanna jump. Jump. Come one Creed."
