Mad Men's Jon Hamm again showed his acting range and comedic chops, hosting his second Halloween episode of Saturday Night Live. This year's costume, he said, was "slightly less nervous" as opposed to last time's "nervous."

The 39-year-old actor's monologue proved that he's just as good as coming up with ad campaigns on the spot as his alter ego Don Draper:

Hamm made a blink-and-you-miss-it appearance in the digital short "Ronnie and Clyde." Rihanna sang in auto-tune as Andy Samberg was "shy Ronnie."

The skit "I Didn't Ask For This" was about embarrassing moments caught on tape. Hamm was Mark, an absentee father on a reality show trying to reconnect with his son. Hamm did his best ridiculously long cry that got auto-tuned. "Now it's a ringtone," he shouted.
