We have to give it up to @ChavalGameplays.  When you are left (in a hotel room? a dorm room?) without a microwave or oven, you have to get creative.  When it comes to eating pizza hot, you should absolutely go to whatever lengths possible to make it as fresh as when it was delivered.  And that is what this brave man did.  So to you @ChavalGameplays, we celebrate your ingenuity.
