Citizen Khan Season 3

Khan is initially pleased when mother-in-law Naani announces that she wants to move into a retirement home and is eager to help her pack. However he finds a letter in her trunk telling him that she is worth 25,000 and decides he will stop her from moving by getting Amjad to dress up as another old lady in order to take Naani's place. The deception is of course rumbled - after which Khan learns that the 25,000 refers to rupees, which make approximately £150.
