And the 5th: eat a nacho hat. (Nacho, nacho hat! I want to eat! A nacho hat!)
1. Take The Ride
Travel to Universal Studios Orlando and take The Simpsons Ride, a simulator ride where you travel through a Krustyland theme park (how meta!) while trying to escape a murderous Sideshow Bob.
2. Manage Your Collection
How many Simpsons collectibles do you own? What condition are they in? And when was the last time you dusted them?
I would suggest that you look up each item's value on eBay, but I don't want to make you cry.
Related: Simpsons memorabilia is, as a rule, worthless (not counting the emotional value). Most of it was produced in the 1990s, which was a high water mark for the production of "collectibles." In the sense of "things which are labeled collectibles but which are produced in staggeringly high numbers thus virtually guaranteeing that none of them will be worth a cent in the future." See also: X-Files memorabilia, Friends memorabilia, etc.
3. Practice Your Drawing Skills
If you play the iPad/iPhone game Draw Something, you might have noticed Simpsons terms sneaking in there over the last 24 hours. This is one of the ways the game's new owner, Zynga, is monetizing it: by charging a fee to add selected keywords to its playing dictionary. In the last day I have so far received "Simpsons" and "Marge" as words to draw. (I'm pleased to say, I think I did pretty well.)
4. Play Video Games
Video games have often been featured in The Simpsons - and vice versa! EA's Simpsons game for the iPad/iPhone, "Tapped Out," was so successful in its first week that they had to pull the game from the iTunes store because players were bringing the game's online servers to its knees. As of this writing, the game is still not yet available. Here's hoping they bring it back soon, because it's apparently pretty great!
But fear not: so far there are 25 other video games featuring everyone's favorite bright yellow family. Out of the entire list, I believe The Simpsons Hit & Run and The Simpsons Road Rage are the two most highly-reviewed titles. But who could resist the opportunity to play an Itchy & Scratchy Mini Golf game on the Game Boy?
