I'm sure a few people have already done this but basically there's this application going around on Facebook at the moment called 'Take this Lollipop'. It's quite weird but at the same point has a valid point; which is that Facebook is not exactly deemed the safest thing on the net. Anyway, click the link below and sign in your account (It's safe), accept the application and what the video. I guarantee you will be like 'WTF!'.
