The "Randall Stretch" should actually be called the "Haigh Stretch" as Drew seems to have shown it to Tom in the first place...
It doesn't work for me anyway. Rename to 'Laying Uncomfortably like Haigh and/or Randall'...?
Seems to work quite well for me. I usually have to wriggle about for a while until I can feel the stretching in my elbows.
