Technically speaking, it is quite possible to bludgeon a tiger
to death with just your fists. They're mammals with a brain, and
the brain is a soft lump of tissue that's suspended in fluid.
Walloping the container that it's in tends to bounce it about a bit
(even when said container takes minimal damage), with predictably
nasty results. Repeated strikes would probably end up causing
serious injury to the animal, and possibly death.
However, we have no clue as to how strong this guy was other
than the hyperbole that often fills such accounts. I believe that a
well-conditioned man with some training could pull this off if he
managed to hang on to the back of the tiger long enough to do the
work. The hard part is not the killing, it's the
surviving.

Now, if only parn
could get mauled by a tiger...
Pah, who am I
kidding, the tiger would retch at the concentrated stupidity and
throw the remains back up.
Why do you need to mention my name? 
But on the other hand, cowards like yourself can NEVER even come
close to me to be able to do anything real to me.
Keep hoping, cos one day you will get run under by a bus.
