Do subliminal audio messages and subliminal messages work?

Yeah, definitely. Have you ever watch Derren Brown? He uses subliminal audio messages all the time and you can see them work. He slips the odd word into a conversation to put in your subconscious thought process. Subliminal messaging in advertising is very common. You would be watching something and a flash of a bottle of coca-cola would pop up. There are whole departments in some psychology universities that specialise in just that as well. Not to mention that there have been studies done what prove subliminal messaging works. I'll include a very interesting video explaining and illustrating this. It's only about 6 minutes long.
