We know the following about Jerry's "move":
(1) You need a headboard on the bed; (2) There shouldn't be more than one inch differential in the couple's heights; (3) Make sure you close with the swirl (no premature swirl, as George found out); (4) Jerry prefers the clockwise swirl (as opposed to the counter clockwise swirl); (5) The copycat used the pinch at the end instead of the swirl.
