I just fell for a Twitter phishing scam -- it took the form of a direct message from one of my contacts, with the message "This you????" and a link to a site that prompted me for my Twitter password (which, like an idiot, I entered before noticing that the URL was twitter.scammysite.com; blame it on browsing with a tiny mobile-phone screen while in line at the coffee shop). You have been warned -- stay away from anything that reads "This you????" or "This you in this video????" Hell, I think that a good rule of thumb is to ignore anything that uses multiple question marks for emphasis. Even if it's not a scam, it's probably too dumb to read.
