What is wrong with the bathroom?

M: Hi Randall.
W: Hi.
M: Come on in.
W: Uh, yeah, uh, I stopped by to see if you were still looking for a roommate to share your house.
M: Hey, let me show you the place. Uh, here’s the living room.
W: Oh. It looks like you could use a new carpet... and those stains?
M: Well. I’ve had a few problems with some former roommates. I know it needs to be cleaned, but I just don’t have the money to do it right now.
W: Oh. And what about the kitchen?
M: Well, the refrigerator door is broken... a little bit... and it won’t shut all the way. It needs fixing, but don’t worry. I’ve just improvised by pushing a box against it to keep it shut.
W: Hmm. Great.
M: Ah. It isn’t that bad.
W: Well, how about the bathroom?
M: Well...
W: No, no. Don’t tell me. The toilet is stuffed or the sink has a few leaks.
M: No, those work fine, but the window needs fixing.
W: The window? Where’s the window pane?
M: Well, that’s a little slight problem. I’ve put up a piece of cardboard to keep out the rain and snow, and if it gets a little cold, you can always turn up the heat.
W: Hey, I think I’ve seen enough.
