5. Window Cleaners
Window Cleaners!? Seriously? Well, lets talk about high rise buildings. You know those enormous towers filling up every city? They are shiny because most of them are all glass.

Instead there is some poor sucker all the way up there dangling from a line with a squeegee. If that doesn’t take balls by itself then wait until a good gust of wind comes along.
