Police called for exhibitionist next door.

This is an old one folks:

The police arrived at the ladies house and followed her to her laundry room.

"Right next door. The man's in his bathroom,fully naked."

The two officers looked out the wash room's window. Next door was indeed a man who appeared to be shaving in his bathroom.

One of them turned to her. "Ma'am, all I can see of him is from the shoulders up."

She gave them a look of consternation, then moved a stepladder in front of the window. "Here, climb up on this and you can see all of him."
