A woman has a problem with her wardrobe closet in the bedroom. Every time a bus passes the house, a door of the wardrobe closet would fall off.
She called a repairman to try to fix the problem.
The repairman comes and see that indeed the door falls off every time a bus passes by.
“Okay!” said the repairman, “I’m going to step inside the closet, you close the door behind me, until I see if I can detect what the problem is, as he steps inside the closet.
The wife closes the door behind him.
At this point the husband suddenly arrives home, and finds his wife in the bedroom, talking to somebody. He rushes upstairs, and opens the wardrobe closet door, sees the repairman, and shouts, “What the hell are you doing in there?”
The repairman meekly replies, “Well believe it or not, “I’m waiting for a bus!”
