Still not as good as "Einstein's Theory of Relativity in Words of Four Letters or Less". Excerpt follows:
A few more of us got it, then. But most of us just said, "What are you two on? Put down the bong and get real! This is way too wild to be true." But they just said, "Just try and see if it isn't true."
So we came up with ways to test old Al's idea, and each time Al hit the gold. His idea had the sun's rays a tiny bit more red than what Izzy said. They were. His idea put Mars a tiny bit off from how Izzy had Mars. It was.
The big one, the one that got told over and over, was the one with the dark-at-day time. You know, when the moon gets in the way of the sun. At that time you can get a real good look at a star when it's up next to the sun. (Next to it in the sky, that is. Not next to it for real. You know what I mean.) They went off and got a good look at a star that was very near the sun, and then they used a book to see just what spot that star was in. You see, the rays from the star pass so near the sun that they get bent, on the way to us. Old Al, his idea said just how much the rays get bent. With Izzy, the rays get bent, too, but only by half as much. So they took a look at the star, and they took at look at the big book, and ... well, I'll bet you can tell me as well as I can tell you just how far off that star was.
A-yup.
And then all of us, we all just sat back and said: "Whoa."
Newtonian gravitational lensing (not sure if that is an actual term). Newton's gravity could be applied to photons to get some lensing, but this predicted was half of that predicted with general relativity
A naive application of Newtonian gravity can yield exactly half this value, where the light ray is assumed as a massed particle and scattered by the gravitational potential well.

What does this refer to?

Exactly half, as it happens.
