Happily ever after.

Pharaoh: please tell me what is this!
Servant 1: our new office. 
Pharaoh: my eyes want to rest right now.
Servant 2: you will be fine.
Hopefully it will be cool soon. 
Servant 1: we see it every day. 
Servant 2: Pharaoh, when you leave work, you will have big smile. 
It's a good thing.

All evening and night. 
Servant 2: especially after big jobs.
Servant 1: we don't have small jobs here.
Pharaoh: king, your servants say, you have big jobs here.
What is it?
King: "choo - choo".
