You think the lengthy approval process and massive amount of lurkers is a worthy issue to poke fun of? A lot of people are throwing around the idea of including classic GAF thread trends etc, which I think is a great idea, but I think the member process has some humor to be mined out of it.
Something like a kid staring at an unopened toy, perhaps an action figure
You can tell he is just dying to play with it, but some ominous adult like figure says, "No you can't play with it yet!, Three more months!"
Then quick cut, text saying three months later, kid opens it and makes the action figure do a FHUTA to another action figure (in a subtle way, not straight up simulated sex but them kind of banging together), then the ominous adult sweeps in, steals the toy back and says, sorry that is a banned meme.
Cut to nice GAF logo (m0dus), "Still can't post?" fade out in to new text, "Maybe someday", fade out to new text, "Believe"
