I don't want to spoil anything but my favorite favorite favorite scene is when they're driving recklessly to get the officer's attention.
Just go watch it. It is the funniest thing I've watched in a long time. Mad props to Kristin Wiig. I had decided to see it because I watched Jimmy Fallon praise Kristin in his genuinely boyish excited tone. Not to mention, I was impressed with Kristin's stylish attire - she is seen here in the interview wearing a sexy halter outfit, with yellow nail polish (yes because I'm a nailpolish-junkie), ombre highlights, and subtle but delicate gold jewelry. I'm not a fashionista, but I was taken aback by this woman who I normally see on SNL as an understated goofball. She's brilliant here, because she not only shined as the star but also wrote the script! Normally, you would think these movies are stupid-funny, but I'd argue that this was clever-funny.
