The gluteus maximus, which makes up most of the butt cheek, is the biggest, strongest muscle in the human body.

The tongue of course. All other muscles can be easily damaged.

The way to test which one is stronger is
to attach each muscle to a
force transducer (which tells how hard
the muscle pulls) and stimulate the muscle
electrically to cause contraction.  

Unfortunately, I cannot find any evidence that
this exact experiment has actually been done.  In humans,
tongue strength and endurance is
increased in trained speakers, trumpet players, etc.
Obviously, heart strength and endurance would be
increased in aerobically fit individuals.

Heart muscle is, indeed, considered muscle, albeit
a different 'type' than tongue muscle.  There are three
types of muscle: Striated/skeletal, cardiac, smooth.
Tongue is striated muscle, like almost all of the
muscles under voluntary control.  Heart muscle
is cardiac.  Smooth muscles typically control things
that are involuntary and squeeze: Our guts, arteries, etc.

Strength and endurance are two different measurements,
as you point out.  And they refer to what you'd expect:
Strength is how hard you pull, endurance is how long
you can keep it up.  Interestingly, the endurance contest
is won by smooth muscle, which appears specially optimized
for very long hard contractions.  Next, of course, would
be cardiac (heart) muscle, followed by striated muscle,
which would vary a lot depending on the particular muscle.

But your question is about strength of tongue vs. Heart.  
The answer to that, I really don't know.  If we're lucky,
someone will read this who has done the experiment, or do it,
and tell us both.

Look- it's not the butt r the jaw or the heart! It's the tongue because the tounge can move and jiggle like crazy without bones. Well, at least thats what I think...

I believe it is the jaw. If I am wrong with that one, then I would say the thigh muscle. Sorry I can't be more specific. Hope this helps some though.
