I have 2.
My friend Eric and I were playing on Poke Floats verses his older brother Tom and Tom's friend Austin (but were all friends so...). He was Doc, I was Link, Tom was Falcon, and Austin was Marth. They had 2 lives each and he was by himself with 2. I'm better than him and he doesn't really like Melee so heres what we said:
Me: Let me get a life!
Eric: No I can do this, Poke Floats is my best stage!
Me: You can't win, it's 2 on1...
Eric: Is that the faith you put in your friends!!!
Me: It's 2 people, I can help if you let me borrow a life.
Eric: No let me do it!
Me: YOU COULDN'T DO THIS, EVEN IF YOU WERE GOD!!!!!
Eric:........... I quit......
Tom and Austin: HAHAHAHAHAHAHAHAHAHAHAH, what was that!!!
Me: Takes life and loses without Eric.
Yeah, we always use that line now, it's funny because I've actually won both of the 2 matches where he has said it to me besides that one...
Here's the other line:
Austin was G&W , I was Link, Eric was Fox, and Tom was Falcon with same teams.
Austin: (spamming sauseges) You can't beat my meat!!!
Me: Ha, My sword beats your meat every time!
Everyone just stopped playing and died laughing, it was perfect timing
