Voice Operated Massage Action
If you fancy the ability to demand a massage at any given moment in time, and have your every command obeyed, you would probably be best advised to get yourself a voice-operated massage chair rather than a wife.

Okay, it won't do everything you ask of it, but what do you expect for.. eh $5,799? Oh, you expect it to do everything you ask of it? Well, if you're willing to settle for a little less, Ubergizmo describe what's on offer:
"The complex voice-activated system is good enough to accept an extensive set of voice commands. I guess we'll be hearing a whole lot more "A little lower to the left – yes, that's right. More pressure at the spine please…" once the Robo Massage Chair in installed in your home. Features include five pre-programmed, 15-minute massage sequences from head-to-toe which can be customized to save up to 20 massage preferences."
Not bad, and in the long run perhaps less costly than a living breathing partner who might volunteer to massage you if you ask very nicely, but only on special occasions.
