Q Meet the Fockers‘ type A grandpa Jack (Robert De Niro) teaches baby grandson Little Jack (now- 2-year-old twins Spencer and Bradley Pickren to use sign language. Is that for real?

A Yes, says Rachel de Azevedo Coleman, of the Signing Time! video series, which teaches American Sign Language to babes as young as 9 months. The theory: The ability to communicate makes tots and parents less frustrated. ”A baby at 14 months can have more than 60 signs, and before the age of 2, hundreds,” she says. The Pickren boys were ST! fans before their audition (and have cameos in the recently released Volumes 4 and 6). As for that other burning question: The tykes were told that their on screen first word, asss-hooole, meant french fries, and they have not uttered it since.
