If you're on a LAN, then you can spoof and get away with it, by listenting for
the "spoofed" address' packets.  On the big wide Internet, though, any spoofed
packet will end up going somewhere else, so you'll never get the response.
This can be OK for some uses of spoofing, including sending "bad" packets to a
server (ping of death style, etc) or getting the target to respond to the
spoofed "from" IP address (indirect DoS?).
