10. The Twins
There are few scenes that feel as predatory as the scene in which Roger invites the double-sided aluminum twins up to his office after hours to join him and Don for a drink. Roger goes from being a cad to a straight-up creep in episode 1x09. The twins are at least 40 years younger than him. He takes full advantage of that, and also delights in his penchant for chasing redheads. Don watches on with detached amusement at a good distance. Roger pulls out all the frat boy stops by running his fingers up and down the girls' skin, buttering them up and making them giggle. The truly slap-worthy moment comes when he asks one of the girls, "Do you love your sister? ...Why don't you give her a kiss?" The tone shifts dramatically. The girl says quietly, "Why do people always ask us that?" Oh, goodness. It's clear at that moment that this is a pretty threatening environment. Roger gets what comes to him, though: at the end of the scene, he's rushed to the hospital for having a coronary.
