the problem here is that "puts" returns nil, so the && (and 'and')  
will not reach the next part of the chain, because all of it resolves  
to false:

 >> puts "something"
something
=> nil
 >> puts("something") && puts("something else")
something
=> nil
 >> def new_puts(str)
 >> puts(str)
 >> true # this will do the trick
 >> end
=> nil
 >> new_puts("something") && new_puts("something else")
something
something else
=> true

so you either re-def puts or use your own implementation of puts, like  
I did in the example above.
