Jerry Seinfeld :
I think that even if you’ve had a relationship with someone, or let’s say, especially if you’ve had a relationship with someone and you try to become friends afterwards, it’s very difficult.
It’s hard. Because, you know each other so well, you know all of each others tricks.
It’s like two magicians, trying to entertain each other.
The one goes, “Look, a rabbit”.
The other goes, “So?
… I believe this is your card”.
“Look, why don’t we just saw each other in half and call it a night? Okay?”
