When Mike offers his old jacket to his teenage daughter, she says that it is no big deal because "it's not like Leonardo DiCaprio wore it". Leonardo DiCaprio did in fact wear Mike's jacket when he played Luke for the last season Growing Pains (1985)
Mike's cell phone has a musical ringtone, and once, when it rings at the Seaver house, Carol tells him, "You know, that's really annoying." The ringtone on Mike's phone is "As Long As We Got Each Other," the "Growing Pains" TV theme.
During the packing sequence during the opening credits, a jacket is placed in a box. The jacket has the "Growing Pains" logo stitched on the back.
