Effects on objects due to a brief relocation of massive amounts of mass

I want you to meet Gary. Gary looks like a human, walks like a human, and talks like a human. But he's not. He's a superhero, or a magician, or... something. He's not really sure. He just knows that he has the mysterious ability to be able to safely transfer the entire mass of an object he touches into his own corporeal frame. Not the matter, just the mass. The effect lasts as long as he remains in contact with the object or he chooses to put the mass back. He can use this ability instantly, either activating it or deactivating it.

For example, if he holds a solid 1-cm cube of gold, he will add 19.28 g to his own mass and be left holding a 1-cm cube of gold-colored air (effectively; the whole effect is kinda confusing, so Gary doesn't like trying to explain it).

One day, Gary gets into a fist fight with Superman. He's kinda concerned about getting hit, so he decides to plant his feet firmly on the ground and... take all the mass of the Earth into his frame anytime his super-powered opponent takes a swing at him.

While Gary gets a kick out of watching Superman's fist bounce off his face, he's concerned about the side effects of having that much mass displaced.

Do objects begin flying/sliding toward Gary? Does the Earth's frame deform or its orbit change? How long can Gary retain the Earth's mass before these effects are noticeable or dangerous, to him or others?

Please help put Gary's mind at ease.

Note: For this question, "the Earth" consists of all terrain features on the surface of the planet, the crust, and all material below the crust.
