Why is that you wonder?
I believe it is due to the composition of the muscle fiber found in everyone's calves. Calves are mostly slow twitch muscle fiber. As the most used muscle group in the body, there is a premium on being able to stand on your feet all day and not topple over. Not much strength is needed for this, but due to the sheer amount of time we are on our feet, our calve muscle fibers have evolved to be pretty muchs slow twitch fibers.
Unlike your triceps that are rarely used except for feats of strength (think pushing a stalled car out of a snow drift), your triceps are predominantly fast twitch.
This means your calves can do an incredible amount of reps given a moderate amount of weight.
and this means your triceps are incredibly strong given their small size, yet fatigue fairly rapidly.
the problem (if you want to call it a problem) with slow twitch muscle fiber, is that, relative to fast twitch muscle fiber, it's overall growth rate is much slower by nature and by design. additionally, muscle grows at rest, but due to the nature of calve muscles (being on your feet all day), calve muscles get little rest. Put the two conditions together, and you end up with a muscle group that responds very anemically to growth stimulus.
The moral of the story is that one must be very very patient to grow calves.
