In a desperate bid to prove to Josh that he can lie convincingly, Brian tells Pete that Tanya fancies him. But when Pete and Tanya arrange a date, Brian has some quick thinking to do before Josh's heart is broken. Brian discovers that lying can cause a lot of trouble, while Mel finds out that telling the truth can, too.
