One of my favorite comedies of all time!
1) It's basically a truly PG, "clean" film
2) Anesthesiologist I work with knows "Nancy's" brother IRL
3) It's Bill Murray being Bill Murray, while pushing the boundaries of Bill Murray-ness, but without crossing the line. By the end of the film, you root for his character.
4) I had a crush on Andie. The fact that she grew up in Gaffney, SC made it even sweeter.
