I came across this hilarious video parody which makes total fun of the advertising and marketing industry. Having a background in these areas I found it a little disturbing that I recognized some of this behavior though much of it applies across many corporate environments. Just a prior warning that this video contains adult language.
And while I'm at it here's an old Monster.com commercial that I thought was funny that you may remember.
And...if you haven't yet mastered Twitter, take a look at this humorous spoof on the show "The Office" called "The Marketing Office" as they try to demonstrate how Twitter works.
