Cut a split in the fur behind his shoulder, across the back just big enough to hook your fingers in. Then, in one smooth motion, pull the hide off till it's over the hind quarters, and the shoulders. Then you can pull it the rest of the way off with out much trouble.
Be carefull to wipe your hands off if you get some fur stuck to them, as it'll end up stuck to the meat while you're pulling the hide the rest of the way off.
I love rabbit, but they definately are the stickiest animals I've ever skinned.
A couple old timers around here dip them in water before they skin'em to keep the meat from being so sticky, but I don't like doing it myself...
