OK so Meet the Parents feels like a lifetime ago, but who amongst us still doesn't throw down the "I've got nipples, Focker, can you milk me?" joke every now and then? In the third installment, Greg and Pam have kids of their own, and Greg has to come face to face with his father-in-law once again for a little family reunion. The awkwardness ensues on Dec. 22. Check out the trailer here.
