The classic 1996 episode of the Simpsons, "Bart on the Road" brings Bart, Milhouse, Nelson, and Milton (I mean Martin) to Knoxville to visit the world famous Sunsphere. 

To honor them I say we build a statue of the four characters at World's Fair Park. They did more to promote the city than anything in the last 30 years. 

If we cannot afford a statue of all four characters, a statue of Milhouse in a wig will do.
