Yet again I go off-topic, this time to give you what's arguably one of the coolest Futurama episodes of all time: Episode 211, A Clone of My Own; the professor celebrates his 150th birthday and realizes he needs to name a successor. Mad-schemes and drama ensues. It may well be the most pure SciFi of all the episodes, and it spoofs a number of more serious shows and movies.
The other reason for this post is that if you click this link, or the one in the previous paragraph, you will end up at a blog that lets you stream the entire show. Now that's how the internets are supposed to work, if you ask me.
