Okay... nobody laugh... but the first time I saw it at the theater, the scene was so damn dark, I really couldn't
tell what the hell was going on. I heard the "pounding", and I thought I saw Jack reach back, and I thought
he was pounding on Ennis's thigh or butt. Kind of urging him on, if you will !!

Or should I say "spurring" him on !

Yee Haw.... ride that bull !!
Don't laugh at me now !!! Or , call the men in the white coats . I have a very active imagination!
