New wardrobe

There is a woman who is married to a trucker. They live in a house next to a train station. Because of his job he is gone for work quite a lot, sometimes even months on end.
Everytime when the trucker comes home he will bring his wife a piece of clothing.
Well after all these years the wardrobe they shared got pretty full and there wasn't much space for the husbands clothes left.

The wife thought: why dont i buy a new wardrobe for my husband while he is gone as a surprise, so he has enough space for his clothes aswell!
The wife goes to a nearby store and buys a beautifull wardrobe and has the company set it up for her. As the employees leave she goes back to her living room. At this moment a train passes by and she hears a loud smack coming from the bedroom. She goes to the bedroom and sees the new wardrobe in pieces.
She immediatly calls the company and tells them wat happened. The company sends back the employees and they put it back together. Then an hour later as another train passes the wardrobe breaks again. She calls the company but they just started closing so they promised her that first thing in the morning they would send someone over.

So the next morning a employee arrives and asks what happened. So if i get this right, everytime a train passes the wardrobe just breaks? Thats right! The woman replies.
Well i'll tell you wat i'm gonna do, i'm going to sit inside the wardrobe and wait for a train to pass to see wat happens on the inside.
The wife agrees to this plan and goes downstairs. Its at this time that the husband comes home from his job.
Wife: oh hey honey i got a surprise for you upstairs.
So the husband runs upstairs and sees his new wardrobe, he opens it up and sees a man inside.
Husband: What the hell is the meaning of this?!?!
Employee: well sir, would you believe me if i told you i was waiting on the train?
