The Spy Who Learned Me

This one was just an okay episode. The last ten years of The Simpsons have had some great episodes, but plenty of just okay episodes as well - much more than the prior seasons.

I think this episode's saving grace is Bryan Cranston as Stradivarius Cain, the American James Bond super agent. Cranston is great in everything from Seinfeld to Malcolm in the Middle to Breaking Bad, and he creates a great character in Cain. The only time the episode really takes off is when Cain is involved. He's a hilarious imaginary friend.

The episode plot is pretty standard, Homer gets hit on the head and ends up with eight weeks paid vacation to recuperate. This, of course, is hidden from the family. But Homer may have more nobler intent than you think.
