Tell Us How It Got There

On one of my many walks, I happened to notice a hole in the window of a new house that was for sale. I had a few ideas of how it could have gotten there, but I thought I'd ask you to tell me and everyone how you think a hole in a window could have happened.

Please give a short scenario of how the hole got there - a sentence or two, or if you wish, 1-2 paragraphs.
Later, I'll tell you my theories.
