Competitive Dad is the best at everything. He torments his long-suffering children, Peter and Toby, with constant challenges they can never live up to.
Sport is Competitive Dad's biggest interest - from cricket, to tennis and fishing. Not to mention weight-lifting and monopoly.
Simon Day said that the character was inspired by a dad he saw once at a swimming pool. He challenged his two young children to a race. Instead of giving them a chance, he haired off across the pool then waited smugly for his stuggling sprogs to catch up.
