Vad är Winston Zeddemore Är doktorsexamen?

På Wiki-sidan för Winston Zeddemore innebär det att han har en doktorsexamen (som börjar börja studera någon gång efter den andra filmen)

As previously mentioned, Ernie Hudson reprised his role as Winston Zeddemore for 2009's Ghostbusters: The Video Game, with both Hudson's appearance and voice being used for Zeddemore in the game. Furthermore, since the events of the first film sequel, Zeddemore has earned a Doctorate and is now addressed as "Doctor" along with his colleagues (this is a possible callback by series co-creator Dan Aykroyd to the film Spies Like Us). During battles on multiplayer, Zeddemore can be heard quipping "That's Dr. Zeddemore to you, punk!" when defeating enemies suggesting that he successfully completed his PhD.
