Pork butt or  pork shoulder here. I whack up an onion coarsely,  lay it  on the bottom of the  crock pot.  I dry  rub the meat with  whatever I've  got (  sometimes  just seasoned salt,  lots  of fresh  ground black pepper,  garlic  powder  and onion powder)  lay that on top of the  onion, and top it  off with  " a beer in the pot", and   generally NOT  the Sam Adam's  Oktoberfest.  Nor the  PumpkinHead Ale.   If there is  an apple in the  fridge, that  gets  peeled and chopped into  the  pot, too. Cover and  let   it cook on low for as  long as it takes.  
When the meat is done, I remove it from the pot and  strain the remainders, save the solids and  maybe a small amount of the " drippings", trying to dump most of  the fat.
Shred the meat when you can handle it ( still warm but   don't hurt yourself), dump the meat and the solids back into the crockpot, and then add the BBQ  sauce of  choice.  I really like Charley Biggs Maine  Apple BBQ.   Reheat the  the   whole  deal to  serving temp, using the retained drippings as necessary  for the consistency desired. 
Bulky rolls/kaiser rolls/ Italian Bread/ Baguette-  hobson's  choice.   Sometimes the  bread part is homemade  cornbread.
Cole Slaw,  baked beans, some   Franks  Hot  Sauce or other optional heat  adjustment , and usually  some  unsweetened  applesauce   just  to  assuage the " healthy eats"  demon. 
One  key to me   IS the cut of meat,  you   won't  get  a good  shred or  the best  robust flavor  from  the leaner  cuts used  for oven roasts. Emeril is   right-- pork fat  rules.  
Dress it up, dress it  down, it's  always  good  eats,  good friends to share with  just  makes it better.
