Actor Darren Criss says the secret to a happy marriage lies in the words "Yes, Dear". "I think for any young man preparing for marriage, it's best to get used to saying 'Whatever you want want dear'," usmagazine.com quoted Criss as saying. "So I'm perfecting my 'Yes, dear,' and 'Whatever you want!' Whatever makes her happy makes me happy."
