Go a step further.
Intuition says believe what you see and intuition says velocities add.
One conflicts with the other, don't rely on intuition.
If you believe what you see then this pencil broken:

If you use GR to calculate the time on Earth vs the time on the Moon
http://en.wikipedia.org/wiki/Gravitational_time_dilation

tf = 1,000,000 years
gravitational constant G = 6.673E-11 m^3 kg^-1 s^-2
Mass of Earth = 5.9736E+24 kg
r = 385000 km (distance to Moon)
c = 299792.458 km/sec

t0 = 994222.168323667

An observer on Earth measures the Moon making ~6 more
orbits around the Sun in a thousand years, as prophesied
by Einstein. You'd think someone would notice by now.

Einstein's pathetic mathematics isn't just counter-intuitive, it's
"believe what you see" crap.
