Honestly, most of Hugh Grant's lines and delivery will make many people (and their mothers) at least chuckling a bit, if not laughing full-out.
Alex: (about his failed solo album effort) Yes, it sold only 50,000 copies. Most of those to my mother. ...Rolling Stone called it, "a crass, contrived effort, not even good enough for a dentist's chair".
Sophie: (reassuringly) Well, I'm sure there were other reviews.
Alex: (nods) There were, there were, but none as good as that one.
