(Gee, sounds like we've entered "Pork-Butt Wedgie Land"...

)
Three little tricks that I use for Pork Butts:
1. Spray or oil the grates just before dropping the meat on
2. Removal Trick #1 = I lift them off quickly, using this process:
2a. Have a large piece of foil (enough to wrap the butt up) laid-out on a jelly-roll pan (I Always rest mine in foil)
2b. Drape a chunk of foil over the meat (top and two long sides) to protect yer hands/gloves for step 2c.
2c. Grab the meat and the foil with my hands and a set of heavy leather gloves
2d. Set it down on the foil and wrap it up
3. Removal Trick #2 = Grabbers / Leverage:
I use a set of cheap stainless breadboard scrapers / dough knives (rectangular pieces of relatively heavy SS with one long rolled edge or handle attached)
Work one gently under the meat from both sides, simultaneously (sort of "clamshell" style)
Use the scrapers to lift the meat and plop it onto the foil in the same manner as 2 above
(I find that the long handles on spatulas just get in the way)
Hope this helps!
