Sometimes new friendship can be an intoxicating whirlwind more intense than any romance. You feel like you've known each other forever, having inside jokes instantly. After a few weeks of laughing, you say in unison the only thing that makes sense at the time: "We should definitely write a movie together." And if you're famous, you say, "Let's go onstage at this Billy Joel concert." Warning: Jennifer Lawrence and Amy Schumer don't come onstage until about two minutes in, so fast-forward, or else you'll definitely have "Uptown Girl" stuck in your head all weekend. And this is the last weekend before Labor Day! It's too risky. Warning over. Enjoy!
