Why not using a block ?

def create_some_variables(*args)
  # Create object_1 and object_2 and initialize with values
  # ...
  # pass them to the block
  yield object_1, object_2 if block_given?
end

create_some_variables(...) do |a,b|
  # Display the values of those variables
  puts a
  puts b

  # do something with a and b
  # ...
end
