Amusing Confusion

I have a pictures friends filter here, which has feeds from various places that are mostly images.

One of those places is thefailblog, a collection of stupidities, generally with the word "FAIL" stamped onto them.

Another is Post Secret, a collection of secrets, sent via postcard.

I just scrolled past several posts from the former, onto the latter, and it took me a couple of seconds to work out why they'd suddenly got a lot less funny...
