Kerching! was a children's comedy drama on CBBC. It follows the lives of teenagers Taj, Danny and Seymour. The programme revolves around Taj's website, Rudeboy, and his money-making schemes. The fictional Rudeboy website sells ringtones, computer games, concert tickets, designer clothes and other merchandise and is central to the plot of the programme. The title of the show comes from Taj, Danny and Seymor's catchphrase "Kerching!", used when they make money through their business schemes. Taj aims to make one million pounds for his hard-working mother, which he finally does in the last episode of the show.
