Subject: Hash sanitization from query - newbie

I need to clean up a hash

[{0=>"BSD", 1=>105, "Operating System"=>"BSD", "count(*)"=>105},
{0=>"SUSE", 1=>99, "Operating System"=>"SUSE", "count(*)"=>99},
{0=>"Ubuntu", 1=>97, "Operating System"=>"Ubuntu", "count(*)"=>97},
{0=>"Unix", 1=>190, "Operating System"=>"Unix", "count(*)"=>190},
{0=>"Windows XP", 1=>92, "Operating System"=>"Windows XP",
"count(*)"=>92}]

You'll notice the first part is an array key value pair and the second
part of each hash is a real key value pair.

How would I go about removing all the 0=> and 1=> references from the
above hash?

I've seen people use inject and map but are a bit lost with regards to
those functions.
