Quote from Jerry in The Stranded
[stand-up:] Jerry: All plans between men are tentative. If one man should suddenly have an opportunity to pursue a woman, it's like these two guys never met each other ever in life. This is the male code. And it doesn't matter how important the arrangements are. I mean, most of the time when they scrub a space shuttle mission it's because one of the astronauts met someone on his way to the launch pad. They hold that countdown. He's leaning against the rocket talking to her, "So listen, when I get back what do you say we get together for some Tang?"
