This is one of my favorite moments in Groundhog Day (quite the under-rated movie, if you ask me). The best line is delivered at the end of this scene (at 5:03). The first time we watched this movie, we had to stop the videotape so I could calm down from laughing so hard. It was probably a good five minutes before I stopped.
(Yes, I know it's Candlemas, too. Give me a break. I have fun that isn't Catholic related sometimes.)
