A 400 lb gorilla escaped from his enclosure and ran amok, at one point punching out a door. It didn't help his composure that everyone panicked when they saw him, a natural reaction I suppose.
Gene Tunney wrote his famous article detailing how he would KO a gorilla after giving him a scientific boxing lesson, so I couldn't help but wonder what he would've have done when a 400 lb domesticated gorilla rushed him at the zoo. This fella had to pull his 400lbs over what was probably a minimum 14' wall. Let's remember that Shack probably can't do a single pull up of his 330lbs, much less haul it over a wall.
Oddly enough one of my earliest memories was at a circus with my Dad when I was about 4 and gorilla impersonator stormed the stands, scattering the locals who were sent screaming. Naturally I also thought he was real, and since he was heading my way I stood up and set my fists to be ready to fight. Alas, a bunch of clowns showed up and did their thing and then the thrill was gone.
From that point on I was constantly pestering my old man with fight questions between different animals, sometimes inserting myself in a mythical fight. I remember at 8yrs I showed him a picture of a male lion I clipped from the paper. I had first showed it to my best buddy at the time, and we decided that the lion could probably take us by ourselves, but together we could beat him up. My dad got a big kick out of that. It's nice to know that Tunney's imagination ran in similar directions.
