Booyah!

Game over.
Congratulations.
Learn anything?
That's right...
I stayed up really late coding this.

Well, let me break it down for you:

You have a total of 78 friends
You requested to guess 78 entries.
4 were skipped due to invalid content (surprising?).
You made 74 guesses.
You got 70 correct.
Doing the math for you, that means you got 94% correct

Beat that!
