A window cleaner fell asleep on the job-while working on the 20th floor of a US skyscraper.Passers-by in Nashville,Tennessee,called the fire department after noticing the man was not moving.Assistant fire chief Lee Bergerson said that it "looked like he just fell asleep."The man woke up after the firefighters tugged on his ropes,then held up a sign from inside the window to get his attention.The cleaner lowered himself to the pavement,where he walked over to an ambulance to be examined by paramedics.Leroy Anderson,who watched the man for 30 minutes before fire engines arrived,said,"I figured he had just either passed out or maybe he had fallen asleep.It's sunny and warm up there,and there's no wind."
