Don gets all the glory, but Roger Sterling (John Slattery) is by far the most entertaining man on Mad Men. Sure, he's been through some rough times, but it's nothing compared to Don's constant existential crises. Even his big problems (like having a love child with his former secretary) kind of get smoothed over with a wink and a compliment; he's absolutely impossible not to love. He's most recently been seen forcing Peggy to have a good time in the old Sterling Cooper & Partners offices, reminding us how awesome he is. Here's everything I — and you should — love about Roger.
