Too vulgar? Sorry, that's life. While most friendships don't typically result in marriage to a stripper or leaving a drugged friend on the rooftop of a Vegas hotel, the good ones have nights you aim to remember, but likely wind up not being able to. The lack of pants, or even teeth, the next morning can be a sign of a damn good time. Nevertheless, no matter how many wolves you have by your side as you wander aimlessly around the desert of life, I can only hope "The Hangover" taught you as much as it taught me about friendship.

1. Shit happens.

2. You're going to get hurt (physically and emotionally).

3. Unless someone is missing, it's better to not remember last night.

4. Bonding over song is the best way to go.

5. True friends will make up for their wrongdoings.

6. True friends will not support your toxic relationships.

7. True friends will argue over who gets Bradley Cooper.

8. True friends will bring out your wild side.

9. Every squad should have a nickname.

10. Every squad will have "that" friend.

11. Honesty is the best policy.

12. Coordinating schedules is essential.

13. Friends don't let friends repeat mistakes... alone.

14. Let loose with your buds every once in a while.

15. Not everyone who shits on you is your enemy.

16. Not everyone who helps you is your friend.

17. You can find companionship in the weirdest places.

18. But, always stay true to your wolf pack.
