Yahoo have debuted this first clip from the third installment of the Meet the Parents franchise, Little Fockers. In the clip, we get to see Greg (Ben Stiller) and Jack (Robert De Niro) talk about genetics. Greg (Ben Stiller) and Jack (Robert De Niro) talk about genetics when it comes to Greg’s twins, Sam (Daisy Tahan) and Henry (Colin Baiocchi) and how a twin can get an extra chromosome from the mother or one from the father’s side of the family resulting in a fart joke!

No doubt this will keep some amused! Little Fockers stars Robert De Niro, Jessica Alba, Ben Stiller, Owen Wilson, Dustin Hoffman, Teri Polo, Barbra Streisand, is directed by Paul Weitz and will be with us 22nd December.
