Fit a harness on grandpa and set him on the ride-on lawnmower to do the yard. If he should fall asleep at the wheel, or start mowing off into the distance, quickly tug him off the back off the mower via the extra long cable attached to his back.
Also works with grandmas.-- benfrost, Jan 21 2006 just tie grampa up w/o the mower...perfect for the older Alzheimer's patients and children alike! TetherPaw..... or Tether Maw?-- Dumb But Tough, Jan 22 2006 A brilliant idea with one tiny flaw... what happens when the extra long cable gets caught in the mower blades?-- moomintroll, Jan 23 2006 random, halfbakery
