It's a nee naa in the sky

Even though this doesn't make the nee naa sign it doesn't half make a racket, and the smell. Wow it's intense. You can smell the diesel where I work.

When they clean it the water spills over the roof and we can see it coming down. We normally have to take a second look to make sure that it is the helipopter as I call it being cleaned rather than it actually raining.
