I saw this on a blog I regularly read. Snapshot of priceline's password hint options (http://www.flickr.com/photos/29640538@N04/3717614282/sizes/o/).
BTW, as dumb (and insecure) as that particular hint is, some of them are pretty good. It seems like a decent hint is one you will remember but aren't likely to have written down and won't pop up for someone googling your name and isn't in a large and insecure (government, institutional, etc.) database somewhere that will inevitably be compromised.
I had to see it for myself so I went to Priceline and sure enough, there it is.
Wow. That hint is... wow.
You know, P. T. Barnum's ration must have increased way past a sucker every minute....
