A woman has a problem with her closet door, it was falling out of its tracks every time a bus was passing by. So she finally called a repair man.

The repairman comes and sees that indeed, the door falls out every time when a bus passes by.

He tells her: "OK, I am gonna see what is going on, just close the door behind me" and he steps into the closet.

A few seconds later, the husband comes in from work, opens the closet and finds the repairman.

Husband: "What the hell are you doing here!"

Repairman: "Well, I know you're not going to believe it, but I am waiting for a bus!"
