Finally, we get our first glimpse today of Don Draper (né Jon Hamm) as Liz Lemon's new love interest in next week's episode of 30 Rock. As we've known for a while now, Hamm plays Lemon's neighbor, an ice-cream-making pediatrician she falls in love with after accidentally receiving his mail. This all sounds so perfect, it makes one wonder how Lemon will screw it up, or what terrible secret Hamm's character might be hiding (presumably he can't be the son of a Depression-era prostitute on this show, too). We know it can't last! He's only signed on for three episodes!
