Subject: dont def need return

Hi
      I was learing Ruby and have code like
Class TestClass
        def getcolors
                arr=["Blue","Yellow"]
                arr1=["1","2"]
        end
end
obj=TestClass.new
puts obj.getcolors

           And the result is 1  2  ..This looks some strange to me since
I have not notice in other languages And if arr1=["1","2"]  is absent
then it puts Blue  Yellow ..So dont we need return .I would like to know
what happens here actually
And another inteesing thing is if I write
return arr=["Blue","Yellow"]    the result i get is Blue Yellow
If I give
return arr=["Blue","Yellow"]
return arr1=["1","2"]   then also I get "Blue  Yellow

   Why?
Thanks in advance
Sijo
