I think I've set a record for the longest lasting milk

The milk in my refrigerator has an expiration date of August 31. Including today, it's 45 days past the expiration date and it's still perfectly fine. I used a cup of it to make some Hamburger Helper a few hours ago. I've had milk last about a month past its expiration date before, but never a month and a half.

What do I win?

Edit: I just checked the milk (October 15) and it now has a slight odor. I dumped it down the drain. R.I.P. Old Milk.
