Um, Yes, that's exactly the problem about it, wasn't that clear? It 
rescues *all* StandardErrors. So you won't notice if something else than 
your NoMethodError - which nil would raise - has happened.
Say your gets raises a BrokenPipe exception or similar since the server 
you were connected disconnects you because of bad input you send. Your 
will never see an exception being raised since that happens in the gets 
you just rescue all standarderrors from.
