Using 2 or more celebs, Here's one between NFL stars Dan Marino and Joe Montana:
Dan: Hey, how ya doin Joe?
Joe: Not bad Dan, how about you?
Dan: Pretty good, I was just over at nfl.com looking up my stats and reassuring myself that I am the best.
Joe: *Polishes one super bowl ring* oh really? That's cool Dan.
Dan: Now, cmon Joe, why do you have to do that?
Joe: do what Dan?
Dan: Clean your ring in front of me. You know that hurts me and burns me up inside.
Joe: Well, why didn't you go out and get one yourself?
Dan: Cause you beat me in the super bowl!
Joe: Yeah one year out of the 17 you played.
Dan: But, that was my only chance!
Joe: Hey Dan. The great ones take advantage of the moment and get their ring or rings in my case.
Dan: But if you gave me your team I could've won 6 super bowls!
Joe: How would having my team stop you from throwing interceptions in the playoffs? You're telling me you could've driven down field when we down 16-13 and drove 92 yards for a TD in a pressure packed situation?
Dan: Well, I could've at least TRIED to do it.
Joe: *pats dan on the back* It's ok Danny. You could've TRIED. I actually went out and did it.
Dan: I passed for 5,000 yards Joe!
Joe: What? oh yeah, yeah, good job Dan.
Dan:

Maybe if Shula ran the ball more than 10 times a game and had a Defense i would have had 5 Rings!!!
Joe: Woulda Coulda Shoulda, *Laughs to himself*
Dan: I know i could kick your Arse!!!
Joe: Maybe you can "Ginny"
Dan: Atleast i don't look like Barry Manilow, *Slaps his knee laughing*
Joe: *Puts on his ring, as he pulls another one out of his pocket* Do you want to talk stats
Dan?
Dan: *Stops Laughing* Yea Joe lets talk some stats!!!
Joe: I'm known to many as the "The Comeback Kid," I engineered 31 fourth quarter comebacks in my magnificent NFL career. I brought the 49ers (26 times) and the Chiefs (5 times) back from fourth quarter deficits to dramatic wins! How many did you have?
Dan:37, *laughs again*
Joe: You threw 111 more picks than i did, *laughs and mumbles, Laces out*
Dan: I also threw the ball 3000 more times, *as he curses Shula and bangs his knee*
Joe: .How many rushing TD's Danny boy?
Dan: Ummm 9 or 10, I'm a QB not a RB, *Starts to pout as he drops to a knee*
Joe: It's 9 Dan and i have 20*Opens his Zipper*
Dan: Can you wear your Rings as you pull my hair Joe?
Joe: Yes DannyPoo, Tell me who your Daddy is?
Dan*As he looks up at the Master* " You are Joe"!
