Have anyone shaved their eyebrow?

Any guy specially? I have very thin eyebrow which I do not like. Have anyone tried shaving them, and did they grew back thicker? How many days it takes to grow just enough so than people (colleagues) don't notice. I think I can take Friday off and then shave mine on Thursday evening and hopefully they grow enough till Monday morning. The only thing grows that fast is my beard. I don't like beards they are so annoying.
