The idea for "Speed 3" came from the writers Graham Linehan and Arthur Mathews having heard of the 1997 film "" but having never seen it, felt the idea of putting the action on a speeding boat was incredibly funny, and tried to find a way to make an even worse idea. This cemented the use of the milk float and having Dougal being its driver, but required the writers to find a means to place Dougal in the role of a milkman. This led to the idea of having the previous milkman fired for being promiscuous with the housewives, and having Ted trying to figure out the mystery of the hairy babies.
