Parental Guidance (2012)

Continuity mistake: In the scene where Billy Crystal is chasing his grandson at the recital, he has day-glow paint on his face. A few seconds later in front of the stage, the day-glow paint is gone.

Artie Decker: OK, hop out.
Barker Simmons: I'm still buckled in.
Artie Decker: Oh, boy. This is harder than one of your grandma's bras.
Barker Simmons: It's not rocket science.

Question: When Alice, Dianne and Harper got in the house she said it was Phil calling but why would she lie when obviously Artie was talking on the phone to her? Also, why did Artie call Alice Mrs. Rosin?
