handling sticky bread dough
For really wet dough, wetting your hands works (that is, quickly dip them in a bowl of water, let the water drip off a little, and keep doing that as you work the dough). Depending on the dough, you could also oil your hands (see the "Is there a reason to NOT use no-stick spray (Pam) for handling dough?" over to the right in related questions). Also helps to be quick; keep your hands moving and the dough sticks less.

And to some extent, you just have to live with it being a sticky mess.
