Miranda isn't your average girly girl. At 6ft 1in, Miranda gets called 'sir' once too often, much to the amusement of her childhood friend Stevie, who manages Miranda's joke shop.
Miranda's mother Penny is disappointed that Miranda runs a joke shop rather than having a proper job. Penny bumps into one of Miranda's old school friends, Tilly, and lies that Miranda has a great new job, so Miranda decides to prove everyone wrong and find a new career. After getting caught by Tilly while helping out as a waitress, she decides to come clean and be proud of her real job, but, thanks to Gary, Tilly jumps to a surprising conclusion about Miranda's employment.
