I guess we want to see the photos to understand what Letterman saw in Birkitt. Nothing great, that is for sure. She must have been good in other ways. It is the same with the Steve Phillips' affair ... he picked a total loser in looks but she must have something else he couldn't live without as he bedded her more than once. For most guys once would probably have been enough. Why Letterman, Phillips and others would risk their marriages, possibly their careers, the respect of their children, respect of the extended families, loss of trust and respect by the general public, is beyond understanding. I always want to ask them ... was it really worth it? For each of these guys that have had sexual relations, in the work place for Letterman and Phillips, is this what you want your biographies to center on every time someone googles you online? What a shame you have brought to your family names and to your sons. Shame on you both. Regina Lasko and Mrs. Phillips are way too good for these guys. I hope they find true happiness and can live beyond the sordid affairs of their husbands.
