Knockin' on Toilet Door

In this film, Knockin' on Toilet Door, a young man has been waiting for a long time - 2 years - to use his toilet, because his girlfriend has been using it. During the waiting time, he has to use other toilets, neighbours' or friends' one. He, who can't always expect when he needs to go to the toilet, has knocked at the toilet door and asked her everyday to come out of the toilet. However, he can get only her reply, "Maybe tomorrow".

This story doesn't make any sense?
Oh, should add "Inspired by a True Story: Woman Sat on Toilet for 2 Years".
