Careful With That There Mouse!

A few moments ago, I clicked on what I thought was the "Don't Falter by Lauren Laverne" thread from New Answers, but I'd actually clicked on the "White men who exclusively date Asian women" thread. I immediately scrolled down (having read the earlier answers) and when I FINALLY LOOKED AT THE SCREEN I thought, "blimey! This thread has deviated off topic!" before finally realising what happened.

Have you ever misclicked with shocking or hilarious consequences?
