Exchange different arrays elements in ruby

Is there any ruby method that I can use to replace two different arrays elements? For instance, I have these two arrays: 

#Before exchange
arr_one = [1,2,3,4,5]
arr_two = ["some", "thing", "new"]

After replacements the elements I am expecting something like this:

#After exchange
arr_one = ["some", "thing", "new"]
arr_two = [1,2,3,4,5]

How can I handle this with or without a ruby method?

If you need to have the arrays stay put (i.e. the values of the variables not change) and exchange the contents, then this should do:

arr_tmp = arr_one.dup
arr_one.replace(arr_two)
arr_two.replace(arr_tmp)

You mean, you want to 'exchange' values of local variables? It's quite easy in Ruby:

arr_one, arr_two = arr_two, arr_one
