A long time ago, I thought the Simpsons was pretty funny. Who wouldn't like Spider Pig after all. If you are a Simpsons fan, you will like these cool stickers available at Etsy right now.
They have a picture of Homer being smacked in the head by the Apple Logo on the back of your iPhone. The downside is if you use a case, no one will see the stickers.
Homer's infamous "D'oh" expletive is also featured. The stickers are shown on the iPhone 3GS, but it should work on any version of the iPhone. You can grab these up for $9.90 each at Etsy and there are only three left right now.
