The page you are about to edit is frequently modified erroneously in one of the following two ways.
Changing the moment the show ends from 31 december 1979 to anything else, particularly 1 january 1980, is incorrect. This has been discussed at the talk page and consensus is that 31 december 1979 is the correct date. Feel free to restart the discussion here, but changing the date without consensus is considered disruptive.
The question of who is yelling "Hello, Wisconsin!" at the end of the show's opening credits is subject to much speculation. Several suggestions have been made (most frequently Danny Masterson and Ashton Kutcher), but so far no reliable sources have been found to support any claim. Adding claims of this nature without citing at least one reliable source is considered disruptive as well.
Edits to this page that are in violation of the above will be swiftly reverted by a regular editor. Repeated violations may result in you being blocked from editing Wikipedia.
