How do you keep bananas from going bad so fast?

[Desiree]

I just bought some bananas on Sunday and whats left of them is brown and nasty! Does anyone have suggestions on how to keep them fresh longer?

The best thing I do is keep them in the dark.

I use them a lot in protein shakes and I got a good tip for that the other day. I was told to peel and freeze them. If you want them fresh, it doesn't help much, but on a hot summer day, frozen's pretty good.
