The great thing about this episode, which sets it apart from almost anything else that I can think of, is that we begin & end it without ever knowing exactly how or why they got into the situation they find themselves in, yet it doesn't seem even remotely strange or - with respect to the suspension of all previously known values that is the universe of It's Always Sunny in Philadelphia - even hard to explain. We are at this stage - assuming we've been following their progress - so familiar with the way they think & argue & seize upon some idea to pursue the point of absurdity that meeting the gang in some walk in closet in some stranger's home they've illegally entered seems ....well, fairly par for the course.
An explanation, but what we can infer from the dialogue, would simply be superfluous
