Every ad plays on stereotypes and "rusty" with his ginger hair, pale skin and thick rimmed glasses oozes dodgy salesman (which is accurate as Arrow are renowned for their slick ads and poor quality products).
For comparison reasons these ads are more annoying and frustrating than Jamsta/Jamba crazy frog ads purely due to Rusty.
Josh: Rusty, Rusty! I love you!
Mark: Hahahah i heard you and him had a casual relationship.
Josh: Lets just say he knows how to keep a customer happy.
