You're in great shape , Keith . Do you work out at a gym ?   Yeah , I do . I guess I'm a real fitness freak .   So , how often do you work out ?   Well , I do aerobics every day after work . And then I play racquetball .   Say , I like racquetball , too .   Oh , do you want to play sometime ?   Uh ... how well do you play ?   Pretty well , I guess .   Well , all right . But I'm not very good .   No problem , Rod . I won't play too hard .
