Pairing data with itself?

[amolo]

I am using Excel 2007 (and Google Docs! ), and I have a data set of values that I need to associate with itself. In short, I have a column of data:

A

B

C

I need some trick - be it a function, VBA, or macro - to duplicate that column, and associate every value with every other value. Essentially, generate two columns like this:

A	A
A	B
A	C
B	A
B	B
B	C
C	A
C	B
C	C

Attatched is an actual example of a data set. I've been mashing my head against this, and figured out a way to make it easier to do manually, but I am struggling and would appreciate whatever guidance can be provided! I have a lot of data sets I need to do this with....
