Jon Hamm on "Sh--head" Justin Bieber: "What the F---, Man?"

Jon Hamm thinks someone needs to smack some sense into Justin Bieber.

In an interview with Men's Fitness, the Mad Men star doesn't hold back on criticizing the 20-year-old singer and other privileged members of his generation.

Justin Bieber: A timeline of bad behavior

"Look at Bieber or whoever," Hamm says of the pop star. "You're like, 'What the f---, man? What are you doing? Why?' There's no one telling those people no, and it's a shame."

Hamm's suggestion? "A mom or a dad or a really good friend who can say, 'Hey, sh--head!'"

Hamm ended his "Get off my lawn" comments by noting: " Life skills are something we're missing... just sh-- you needed to learn in life. There used to be a class that kids had to take in high school called home economics, which was cooking and sewing and just sh-- you needed to learn in life."

Bieber has not responded publicly to Hamm's comments. What do you think of his remarks?
