No, the real Abed isn't nearly as awkward or insane as the Abed from Community, but he's certainly just as obsessed with pop culture. Even so, it's hardly a flattering portrayal of the real life version, but he's certainly better represented than many other people who had fictional characters based on them, as evidenced by this great Flavorwire article.

Why's that? Abed's the most wonderful character I've seen in at least 17 years.
