One day a man comes home from work to find total mayhem at 
home. The kids were outside still in their pajamas playing in the 
mud and muck. There were empty food boxes and wrappers all 
around. As he proceeded into the house, he found an even 
bigger mess--dishes on the counter, dog food spilled on the floor, 
a broken glass under the table, and a small pile of sand by the 
back door. The family room was strewn with toys and various
items of clothing, and a lamp had been knocked over.

He headed up the stairs, stepping over toys, to look for his wife. 
He was becoming worried that she may be ill, or that something 
had happened to her. He found her in the bedroom, still in
bed with her pajamas on, reading a book. She looked up at him, 
smiled, and asked how his day went. He looked at her bewildered
and asked "What happened here today?"

 She again smiled and answered, "You know everyday when you 
come home from work and ask me what I did today?"

"Yes", was his reply."

She answered, "Well, today I didn't do it!"
