very Nice Parodies of two nice movies and 2nd best of the season
23 March 2009 | by (Australia) – See all my reviews

Its a very nice parody of National treasure and Da Vinci Code............ my 2nd best episode of the new season where....1st is Mypods and Broomsticks....................Very nice parody of maggie being a good child to bring peace to the world.....and to the end of the episode Bart being the evil child who destroys the cathedral with the help of Setan.........there are many other funny moments throughout the episode.....including puzzles and cryptic clues parodies..and eclipse scene with kent brockman losing it on live making fun of solar powered equipments

......I will highly recommend it to of the best parodies by simpsons ever

the Description of the show is...

Lisa infiltrates a convent in order to steal back Maggie who was accidentally taken in by nuns. While in the convent, Lisa uncovers a series of cryptic clues leading to a hidden jewel in Springfield. With help from resident history buffs Principal Skinner and Comic Book Guy, Lisa sets off to find the coveted prize. But Springfield's Freemasons are also hot on the trail of the jewel, and Lisa must race against them to find the jewel and rescue Maggie.

I know people are complaining about simpson not being as funny as they had before........come on guys its 20 years they have been on air the longest in the history.......they cant make you laugh every single time.........and there have been some not so funny episodes in the past as well.....they run out of ideas some times and has to fill the gap with some nonsense........let us see how long they can hang around...still worth to watch
