You know that hole the President drilled?

Turns out it didn't go through the pipe. 
  No hole where the president had drilled! 

Where's the leak? 

Above the place he drilled there was a screw that held the old transfer board. 

While the old transfer board was in place, the screw that held the board
created but also plugged a hole in the pipe.

When the screw was removed, the hole was unplugged.

We discovered a leak when one of the showers was turned on upstairs and

water was coming out of the light switches.

I blamed the President. He took responsibility.
The Facilities Management people found the leak. 

Vindicated!
