BBQ Pork (not to be confused with Pulled Pork)

My mother has made this for years. It is amazingly delicious. I was a very picky eater growing up, but even I ate this up.
For time's sake, I decided to test it as a crock pot meal. Oh yeah! Excellent. Mom used to spend hours doing this the arduous way with the oven and stove top. Not me, I like my supper to cook while I take a nap.

Here's what you'll need:
3#          pork roast
2TB       butter
1/4c       mutilated onion (we used about 1 cup, and it was awesome)
1 bottle  chili sauce (look by the ketchup at the store)
2TB       brown sugar
1tsp       mustard powder (not to be confused with mustard gas)
2TB       W. sauce- you know the one. You can't pronounce it either.

Get out your finest crockery and dump it all in.

High for 4 hours
Low for 8 hours

Using your tongs, chomp it up.
Put some rice on to cook.
Crack open a can of pineapple rings

Eat until you have to unbutton your pants.
Then take two more bites.
