One day, when I came home from work, I accidently put my car key in the door of my apartment building.

"One day, when I came home from work, I accidently put my car key in
the door of my apartment building... I turned it... and the whole
building started up.... So I drove it around.... A policeman stopped
me for going to fast... He said, 'Where do you live?'... I said,
'Right here'... Then I drove my building onto the middle of a
highway, and I ran outside, and told all of the cars to get the
hell out of my driveway."
