Metahumor is generally frowned upon. Sometimes it works, most of the time it doesn't. Additionally, I doubt many people will get reference, the image is far to small to make out on most computer screens. If your reader doesn't get the reference, the article reads like meme-laden random drivel.
As for the article, it had too much random biography and meme references and not enough jokes. The metahumor makes the meme references ok, but you need more jokes in the article.
I didn't get the reference until after I read the whole article and looked closely at the pic in the featured article template. Even then, I couldn't tell what in the name of Oscar Wilde it was. I had to save the image then look at it zoomed in to tell that it was a picture of Mr. Potato Head. I though it was Frylock from ATHF originally, probably from the word aqua in the image name.
This article might be hard to improve to a high quality. I've seen worse concepts on pee review, and its no hard to fix that I'd advise cutting your losses and trying something else, but it will be an uphill battle to make this a good article.
Prose and formatting:
The infobox isn't formatted right, you can see error messages in it. I doubt that was intentional, and if it was, it doesn't work.
The lack of an image of Mr. Potatohead is the chief reason for this low of a score. The subject of an article should almost always have his/her/its image somewhere in the article.
Average of scores
Try to make the reference more apparent. You might be an uphill battle because most users don't know what the image in the featured template actually is. Maybe if you have that image plus a blown up version of it somewhere, readers might "get it" easier.
