Everybody Loves Raymond is not my favorite sitcom, but it's funny enough that I keep watching it.
One thing I don't get though: Raymond's parents are obviously a huge drain on Raymond and Debra's energy, and highly abrasive to their nerves. Understandable, I know I would never stand for those parents for a day. So why don't they just kick them out? Just march them nicely to the door and say: "OK now, you can come back at Christmas. You'll have four hours then. If you behave nicely."
In real life too, many people will put up with anything for any length of time, from people they don't even like! Why? Usually the worst thing that can happen is that the people will never speak to them again, and isn't that a step up? I don't get it, I never did.
