I love xkcd. This geeky comic almost never fails to bring a smile to my face. But every now and then the comic is so abstract and cryptic that I have no clue what they’re talking about. This strip in particular had me scratching my head until i found this post by Jenner on the xkcd forums:

Examples of Bel-air vs Reverse Bel-air is as so:

Bel-air:
I ate some pretty bad food at this really dingy diner last night and I think I may have gotten food poisoning. I’ve been up all night with a stomach ache and lets say nothing about what’s been going on below that. I just don’t understand /b/, what should I do? I mean, it wasn’t like I ate that much of it. I just got in one little fight and my mom got scared and said you’re moving in with your auntie and uncle in Bel-air.

Reverse Bel-air:
Now this is a story all about how my life got flip-turned upside down and I’d like to take a minute just sit right there I’ll tell you how I got arrested for soliciting a minor while just waiting for my nephew to get out of elementary school with my stereo blaring. It’s tragic really, serve and protect my butt.

As you can see, the Bel-air melds the song into the end of the conversation, and you suddenly realize they’re singing Fresh Prince. Whereas the reverse starts with Fresh Prince and then merges in the relevant conversation.
