Re: Help me understand this SIMPLE Ruby code, using puts in a def

I agree with Sam:

>> def message
>> "this is working"
>> end
=> nil
>> puts message.upcase
THIS IS WORKING
=> nil

>> def message1
>> puts "this is working"
>> end
=> nil
>> puts message1
this is working
nil               <----- extra nil
=> nil

Since the nil is the last thing that is read in the method, upcase is 
called on that nil and upcase throws an error b/c you can't use that 
method on a nil. Make sense?
