How about showing all the different kinds of PVs. Their advantages and disadvantages. Why you carry the ones you do.
You could show passthroughs, 510s, 808s, 901s, box mods, pipes, etc. Explain how some kinds are too expensive for the common user. How 510s are the most common and easy to find assessories. You get the point, now you can ignore it. I guess it was a stupid idea, but it still counts as a suggestion, right?
edit: Having used cat fur as a carto fiber filling, I would not suggest trying this at home. It works great for a while, but the hair gets batted up into lumps if you're not careful. Also if the juice gets too low and you burn your carto, the smell of burnt cat lingers for days.
But a video on safely shaving a cat would be informative and fun to watch.
