Okay, here is my serious contribution...
1986 Kenworth T600 Aero.
This truck was the first to use the slope-nosed aerodynamic design common in almost every make of truck on the road today. Nicknamed Aardvark, Slop-nose and Ant-Eater, it wasn't well recieved by the trucking community in its early years, but as the aerodynamic design improved fleet's fuel milage, people got on board. The T600 line is still made today, almost 20 years later, and has been one of the most successful lines for the Kenworth nameplate.
