My wife LOVES them.  I hate them.  Back story -  
I worked at McD's while in HS in the early 80s.
My 2 or 3 night schedule was almost always as 
a closer, and I would get stuck having to do cleanup
and dishes.  The stainless warming trays that they
kept the McRibs in were always the biggest PITA to 
clean.  I hated the sticky sauce, and was also not a 
fan of onions and pickles on my BBQ sando.  
HOWEVER - we would improvise things a little on occasion
to create things of our own.  We were making Grand Macs and
dbl 1/4 w cheese years before they ever hit the menu.  That 
preformed pork patty used in the McRib made a great sando 
when you put it on a regular bun with mayo instead of the 
disgusting sauce, a slice of tomato, lettuce and cheese.
