Check out a very funny re-lip-synced version of one of the year's biggest hits, Jessie J's "Bang Bang." I've seen a lot of these over the past two years, but this is one of the funnier ones!

Reminder: This is a FAKE video. That isn't actually Jessie J performing the song. Fun fact: the singer actually saw the above fake video and had a very classy reaction to it.
