Subject: Stripping symbol character from hash turned to array

Hi, new to programming and Ruby and trying to work through some problems
and understand the language. Right now I'm doing work with hashes and
ran into a question.

Took this Hash

people = {
  :fred => 23,
  :joan => 18,
  :pete => 54
}

and turned it to an Array via  "people_array = people.to_a"

now I have

people_array =  [[:fred, 23], [:joan, 18], [:pete, 54]]

If I want to keep it as a nested Array how can I go about stripping the
":" from what used to be the key. Please help and if possible, explain.

Thanks,

Emeka

PS
I've tried gsub, but I get undefined method for Symbol

1.9.3p194 :140 > people_array.each do |k, v|
1.9.3p194 :141 >     k.gsub!(':', '')
1.9.3p194 :142?>   end
NoMethodError: undefined method `gsub!' for :fred:Symbol
  from (irb):141:in `block in irb_binding'
  from (irb):140:in `each'
