Smooth ways to ask for a crushes cell number!?!

I have a really big crush on this guy I work with. I at least see him everyday, and we sometimes talk. I really would like to get a hold of him out of work. We do chat online seldomly, and when we do my heart races with happiness.

I would love to get his number so we can text, or just talk. Any ideas on a good way to ask for it?

Thanks you so much everyone,
