I'm sorry but I didn't find it very funny at all
I think I might have smirked slightly at one part, but yeah. It sort of seemed based on the authors too, with things like the brother chatting on webcam to a gothic canadian girl with a baby. Those sort of things just stuck out as too awkward for me, I don't know how to properly explain it, it just came off as weird and didn't help with the delivery of any of the humour.
The art-style was pretty generic, the animation wasn't amazing but it did the job. I think the best part for me was the dream sequence, although kinda out of place with the rest of the flash it was the most entertaining of it all for me.
