W: Anything else？
M: Nope, that's all for now. Hey, honey, you know, they're organizing a company basketball team, and I'm thinking about joining. What do you think？
W: Humph.
M: "Humph"？ What do you mean "Humph"？ I was the star player in high school.

M: So, what are you suggesting？ Should I just abandon the idea？ I'm not that out of shape.
W: Well...you ought to at least have a physical before you begin. I mean, it HAS been at least five years since you played at all.
M: Well, okay, but...
W: And you need to watch your diet and cut back on the fatty foods, like ice cream. And you should try eating more fresh fruits and vegetables.
M: Yeah, you're probably right.
