My  boss  had  a list of e-mail addresses with a lot of duplicates. He
 wanted to get rid of those. He assumed that this is an easy task for a
 computer savvy person, so he asked a developer to do the job.

 The developer began working on this. Sadly, my boss was in a hurry and
 the dev wasn't quick enough. So my boss ran to me  and  said  that  he
 wants to get the job done right fucking now.

 Well.

 I copied the addresses from a Google Spreadsheet into a textfile.

   1   $ sort <data | uniq >foo

 I copied the new file back to Google.

 My  boss  watched me do this. Of course, the whole thing took about 30
 seconds which was ...  well,  not  as  much  as  the  20  minutes  the
 developer had already spent on this. Boss starts laughing. Boss starts
 ranting about devs. Boss hugs me.

 Well.
