The difference between Advertising & PR

I have just read a funny post from Chris Brown in the US.

Here are pics from it - I think it is self explanatory !

Just one comment I would add though. Something I have been beating on constantly in this blog. It's the power of repetition from different sources. Joke apart the subject is more likely to believe the statement to be true if he hears the same info from at least 3 different types of sources. So Branding / PR and Advertising should be used together to consolidate the brand message... one really can't achieve the same results alone.
