2006 was a year in the 21st century.
In this year, Emmett Brown was signing a contract with a banker named Mr. Friedman in order to keep the Institute of Future Technology open. However, Professor Frink came back in time in one of Doc's rebuilt DeLoreans and ran Mr. Friedman over, ending the contract. After that, Doc had to sell his institute to Krusty the Clown, and was offered the job of ticket vendor for Krustyland.
