Two police officers responding to a domestic disturbance with shots fired arrive on scene. After discovering the wife had shot her husband for walking across her freshly mopped floor, they call their sergeant on his cell phone. 

"Hello Sarge.

"Yes.

"It looks like we have a homicide here. 

"What happened?"

"A woman has shot her husband for walking on the floor she had just mopped."

"Have you placed her under arrest?"

"No sir. The floor is still wet. "
