Select Random Row from Separate Sheet without duplicating selected rows

[ydnad_2010]

Hi All,

I have this daily task where i manually assign each TASK to each team (color names) which i find it tedious because of the long list of tasks.
Below is a sample sheet (Sheet1)
Column A Column B Column C
TASK ITEM ASSIGNED TO
Encode Page1 Red
Encode Page2 Blue
Encode Page3 Yellow
Encode Page4 Orange
Encode Page5 Green
Encode Page6 White

What i want to happen is that, I'm looking to generate a formula on a separate sheet (Sheet2) under Column B, it will randomly pick data from Sheet1 Column B (ITEM) but will not duplicate the selected item. Same with the ASSIGNED TO column.

Column A Column B Column C
TASK ITEM ASSIGNED TO
Review ??? Red
Review ??? Blue
Review ??? Yellow
Review ??? Orange
Review ??? Green
Review ??? White

I hope i got the explanation right.
Thanks,

upload an example sheet please

See attached. the team colors are assigned as sheet names... where the function should be added on those sheets under column B.
One thing also is that the Assigned to should not be getting what was assigned to them on the main Sheet1.
