   • 2006, Duff Brenna, The Book of Mamie, page 195:

     I pinched a cowlift over Jewel's hipbones. Then we took a chainfall and hooked it to an overhead beam and then to the cowlift.

   Get that chainfall over here. We're gonna flip this damn thing over. We'll be here all week if we don't get better access for this grinding op.
