How wonderful it must be
To be a cheerleader.
Think about it:
1) Because they are cheerleaders, all they had to do was allow Fern into their ranks to get the guns cheap.
2) Because they are cheerleaders, they had something to bargain with for Lisa's help after being arrested.
3) Because they are cheerleaders, they had the acrobatic training to blot out the security camera (and be confused with Chinese acrobats).
(Mind you, I think this is one of the main points of the movie)
I'm quite a lovely person - apart from my terrible taste in pie.
