series plagiarizes itself. That occurs here when Mr. Burns states 'There’s a new Mexico?', a line that was a lot funnier...back in season five. Bad sign number two: a scene in which Homer gets raped by a panda. A couple of the pranks provide minor amusement, but overall, this is a weak episode." Judge Mac McEntire of DVD Verdict said the episode's best moment was with Homer and the panda. Mike Scully believes that the episode's negative reception was due to critics and audiences being unfamiliar with The Magic Christian. In January 2012, Johnny Dee of The Guardian wrote that many fans regard the panda rape scene as "a low in the show's history" and suggested the phrase "raped by a panda" should replace "jumped the shark" to imply that a popular series has declined in quality and is beyond recovery. Cultural references The chalkboard gag reads "I was not the Sixth Beatle", a reference to the "Fifth Beatle". The chalkboard on The Simpsons: Christmas 2 DVD reads "I will not surprise the incontinent". This is the chalkboard gag from the season 12 episode, "Insane Clown Poppy". The episode's plot is similar to the film The Magic Christian: The main character, Sir Guy Grand, is an eccentric billionaire who bribes people to carry out his whims, similar to Mr. Burns' hiring Homer to be his "prank monkey". Grand also plays his pranks to shock people, mocking what they consider to be important, similar to the prank that Burns and Homer play on Comic Book Guy. In celebration of Bart's "A" on an astronomy quiz, the waitstaff at The Singing Sirloin sing "Happy First A", a parody of "Happy Birthday". When the Simpsons are pressed into service as a Mariachi band to pay for their meal at The Singing Sirloin, they are heard playing: "La Bamba": Best known for its covers by Ritchie Valens in 1958 and Los Lobos in 1987. "Spanish Eyes": Originally an instrumental titled "Moon Over Naples", it was re-titled to "Spanish Eyes" when lyrics were added. Singing Sirloin employee Mary Kay seems to be a reference to the Mary Kay company, judging by her pink makeup and all-pink outfit. When Smithers asks Mr. Burns for time off to produce his Malibu Stacy musical, Burns laughs and sarcastically asks, "Why not write a musical about the common cat? Or the King of Siam?", referencing the musicals Cats and
