Well, I'm not sure this is my favorite kiss ever, but it's eclipsed pretty much all other kisses when it comes to sheer hotness factor. I'm not a Skate fan anymore -- in the last couple seasons of Lost I became a definite Sawliet girl. But this kiss? Holy cow. I'm amazed they actually showed it on network television. In fact, you might not want to watch it -- it might cause your monitor to melt.
That's from the season 1 ep "Confidence Man." Hmm. Maybe I should rewatch season 1 now that I've seen the whole series. Oooooh, tempting!
