Long running and well past its prime, The Simpsons with "Homer and Ned's Hail Mary Pass" gives us two ideas recycled from fresher years. Homer becoming a mascot via dancing was done before and better in season 2's Dancin' Homer. Homemade movies, Ned's with a religious theme, was done before and better in season 6's A Star Is Burns. Side note: Lisa being straight faced about Homer mooning was done before and better in season 5's Rosebud. This episode stands out for one reason only, the reveal Comic Book Guy's name is Jeff Albertson. This is dropped extremely casually after 16 years in an obvious attempt to tick off long-term fans, something I will give points for (he does look like a Jeff Albertson).
Some things are worth a minor chuckle; The Mario homage, omelets made from the eggs thrown at the Simpsons' house; Homer and Ned's church talk. Secular humanists complaining Christians are shoving their message down their throats (usually the Christian right is complaining it's the reverse).
That said, there are several points in this episode that, in addition to being unfunny (and most of it is very unfunny), rub me the wrong way. Homer wasn't always a jerk to the degree he is gloating over his victory over Bart. Bathroom humour sucks as always. I won't say "Worst episode ever," partly because it wouldn't be true, and partly because I don't want to be compared to Jeff Albertson.
