I've always enjoyed it, but having it on in the background while I had to clean up the result of a clogged drain + dishwasher = overflow all over the kitchen, immersed in my own exhausting and seemingly endless despair via frustration gave me a new appreciation for it.
In high school a friend of mine was trying to think of this movie and couldn't think of the names of any of the actors or what it was about and I still got it right. I think his description was "Guy from Chistmas Vacation and the Guy from Ghostbusters and there's a clown."
Also: Really underrated I agree.
