We just love Apple's impish "Hello I'm a Mac. And I'm a PC" ads and the way it takes light jabs at Microsoft's operating systems. Now that Apple's new OS X Leopard ad has been up and about for some time now, its time for a new Get a Mac ad to let Apple owners - and potential owners - ROFL at Microsoft Windows users (not that we condone making fun of other people).

In this new ad, PC gets a referee to evaluate both him and Mac. There's even a nicely-inserted Wall Street Journal reference for those who closely follow the light banter between Apple and Microsoft's operating systems.

If this new Referee advertisement made you want to check out similar ads, then you shouldn't miss the one featuring Gisele Bundchen.
