I was randomly fooling around with the "inspect element" function of Chrome and played with my MileagePlus 2014 summary page.

Details of the changes:
Global Services Member
10 Million Miler
Star Alliance Gold
Award mileage balance: 1,123,198,128 (that's billion with a B!)
Lifetime flight miles: 5,237,317,734 (still a B!)
Over $12 million in spending in 2014

Of course it's all fake, but I used their existing settings so it's pretty much what the real version would look like.

Can't think of any practical use, but still fun!
