Editor's note: This classic film gave us the line that’s useful in so many situations, expertly delivered in a cameo by the director’s mother: “I’ll have what she’s having.” It comes after an already-hilarious scene that could have stood alone, but it’s the cherry on top that pushes this movie from great to immortal. If you want to laugh, cry, and ponder deep truths about friendship, love, and marriage all in the same movie, you’ve come to the right place. Get your When Harry Met Sally wallpaper and enjoy!
