FishbowlLA has an exclusive on who will be joining Jerry Seinfeld in Microsoft's new ad campaign.

Our insider says the whole campaign is focused on 'everyday' people using Windows in real situations. Some of the options the agency has been floating around have been a reporter on Humvee, an Obama/McCain speech writer, a DJ - a blues musician. There was a crew that traveled all over the world filming humanitarian workers.

Not to be out done by 'real people' there are tons of celebrities that the campaign may also feature. At the moment the names that have been put into the mix are Sarah Silverman, Willie Nelson, motorcycle rider Travis Pastrana, Matthew McConaughey and Ralph Nadar. Also in what seems like a direct answer to the Mac campaign - Rob Corddry and Stephen Colbert may also do a spot.

Most notable of the names is that of the late great Bernie Mac (insert lame pun 'burning Mac' here).
