On the November 19, 1999 episode of Millionaire, Carpenter proceeded to advance to the million-dollar question without using any lifelines. He then used his Phone-A-Friend to call his father not for help, but rather to tell him he was going to win the game. Carpenter answered the question correctly and became the show's first millionaire. His win gave him national recognition and led to multiple talk show appearances, as well as reappearances on Millionaire himself.

Is it true that has anyone ever won a million dollars on the show who wants to be a millionaire?
yes
