--> Summary on [=FanFiction.Net=]

''[[http://www.fanfiction.net/s/2156084/1/Another_Prisoner_Another_Professor Another Prisoner, Another Professor]]'' is a ''Literature/HarryPotter'' [[Main/{{Fanfic}} Fanfic]], written by Marauder. It starts off as a retelling of ''Literature/HarryPotterAndThePrisonerOfAzkaban'', with one difference: Sirius Black and Remus Lupin have switched places.

A simple premise, but this fic does more than switch the names around. It comes with its own subplots, and is [[OriginalFlavor written in precisely the same style]] as Creator/JKRowling.


!!''Another Prisoner, Another Professor'' provides examples of the following tropes:

* DoesThisRemindYouOfAnything: "No one chooses to be a werewolf."
* [[HasTwoMommies Has Two Daddies]]: If everything is going well, Harry might end up living with Remus and Sirius.
* NoSuchThingAsWizardJesus: There's a discussion about religion, and a chapter even takes place in the magical version of the Catholic Church. Jesus, however, isn't stated as a wizard.
* RoomFullOfCrazy: Remus' cell in Azkaban is filled with Harry's name written in blood. [[spoiler:Later, it turns out that it was a ritual to protect Harry.]]
* STDImmunity: His lawyers think that Sirius has a VD, but since magical people doesn't usually contract muggle diseases, [[spoiler:Ron thinks that he had actually developed lycanthropy.]]
* TamperingWithFoodAndDrink: Kreacher often does this to Sirius. [[ItMakesSenseInContext He puts chocolate into his master's food]] because Sirius is allergic to it.
