Lrr's wife is mad at him because he has not conquered any planet. Lrr goes to Earth to try and conquer it, but nobody takes him seriously. So, the Planet Express crew stage him taking over Earth, but when his wife finds out, will Lrr confess he has not taken over Earth?
Good episode. Comic-Con was funny. Bender's question about a second Simpsons movie was pretty funny. And Nndn thinking Lrr was into Leela was good. And Fry's plot was good. Overall it was a pretty good episode. B+ or so methinks is adequate enough. Not horrendous not perfect methinks
