Repairman
A woman is having a problem with her closet door, it was falling off every time a bus was passing by.
So she called a repair man.
The repairman comes and sees that indeed, the door falls off every time a bus passes by.
“OK, I’m going to see what is going on, just close the door behind me” and he steps into the closet.
Just then, the husband comes from work, opens the closet and finds the repairman.
Husband: “What the hell are you doing here!”
Repairman: “Well, you’re not going to believe it, but I’m waiting for a bus!”
