We all have done it, singing at the top of your lungs to your favorite song, and someone catches you singing the wrong lyrics.... BUSTED!

So much for being the coolest person in the room. Well, don't feel so bad I have found a hilarious montage of 20 videos with a little spin on the lyrics.

Some of these make perfect sense and some you may go say what?  Click link here to  see them all.

I am not sure If Christina Aguilera has seen this, but I hope she does and get's a chuckle out of it. (Warning: some of the clips in the video are of an adult nature, may not be safe to watch at work)
