It is OK for girls to fart in front of guys.
So says Jon Hamm, the star of hit television show Mad Men, who has dished out some surprisingly honest and sensible advice in a new "agony aunt" video for teen girl website Rookie.
The hilarious video sees the 41-year-old sex symbol answer questions like "do guys care about a girl’s style?" and provides advice about what to do if a girl's boyfriend doesn't want to do "stuff".
He also gives the verdict on that old chestnut: "If a girl farts in front of her significant other, should she feel embarrassed?"
"No of course (not)," he says. "Everybody farts."
The video was part of a series for Rookie called Ask A Grown Man which has also featured actor Paul Rudd.
"I hope I've been helpful," he says at the end. "I'm 41 years old.
"It doesn't mean you have to pay attention to me.
You're probably all too young to watch Mad Men, so I don't know. Enjoy The Hunger Games."
