We all know the movies; Baby Mama, Mean Girls, and, airing soon, Sisters. These two hilarious ladies can often be found side by side on a cast list, and also in life. Since you and your best friend are also hilarious, I'm sure you two can relate to these situations:

1. When you prepared her for her first date.

2. When you two had to explain your actions from last Saturday night.

3. When you thought you heard someone say a quiet remark about one of you.

4. And when you realized that someone did indeed say something about one of you.

5. When you saved her from dying her hair that awful color.

6. When you arrived home from yet another successful night out together.

7. When you first said the words that made you realize you two were going to be best friends.

8. And then when you realized you both hate the same people.

9. When you constantly repeated "I can't take you anywhere" to her.

10. When you stuck by each other's side through the awkward middle school stage.

11. When you went with her to Yoga and Palates because she said it would be fun.

12. When you successfully pulled off a surprise birthday party for the her.

13. When you picked dates with each other over dates with boys.

14. When you two stuck together through the "duck face" and "tongue" selfie phases.

15. When other girls tried to mess with her and you always had her back.

16. When you were forced to do school presentations together.

17. When you shared your social media passwords with each other.

18. When you asked her for advice but you didn't actually take it.

So, let's face it. We all have a little bit of Tina and Amy in us.
