Compulsion: (Noun) An irresistible urge to behave or performs actions in a certain way against one's conscious wishes.

Regular readers may have noticed a little pattern around here by now. I post entries about Spencer Pratt and Heidi Montag, you guys leave comments that say "Please stop writing about these people" and I continue to post about them anyway.

But just so you know that I'm not the only one sickly obsessed with them, check out David Letterman's interview with Mary Kate Olsen last night. Letterman, as you may know, had Spencer on the show recently, and incredulously skewered him for five minutes. So naturally, when Letterman speaks to Mary Kate, he's less interested in her new film The Wackness, and more interested about the fact that she went to high school with Spencer Pratt. After he gets her to admit that he's "wormy" and that he had a bad temper during soccer, she kind of stops responding to him while he continues to interrogate her about what a turd he is anyway. And yes, it is awesome. (5:00 into the clip.)

Mary Kate, for her part, has a good sense of humor about it, and laughs it off. Side note: anyone else think it's weird to hear her speak? She's pretty annoying in a hippy-dippy way, but kind of funny at the same time. Hmm. The jury's still out on this one.

Anyway, here she is on her way into the studio showing off her cute little gams:
