It has happened.

One time I swore I was posting a picture of my desk and accidentally posted a photo from earlier that day of me in the shower. My boyfriend called to tell me but refused to help me remove the photo.

Another time I had Flicker and it automatically uploaded photos from my phone to the stream. I did not know this when I took a picture of my bottom to see if I could read the words on my undies.

Oops.
