Nine images below the cut.
There were two scrolls set up so that you could write down your theories and memories of the HP books. Here are a few that I found amusing...
On the Memory scroll.

Dolores! My dear Dolores! How I will miss you. Even if the world thinks you're awful, I adore you. -Joselle (yep. I signed my name to that) P.S. In my little world, you are the next Minister of Magic. Screw Scrimgeour!
There were no cat macros involved, so
julian_black supplied one.

And Sasha provided a lovely illustration.

On the Theory scroll.

Harry in the study with the candlestick.

Harry is the Fifth Element.

Frodo throws Snape in fire of Mt. Doom, oops, wrong book, movie, film, oh bugger as long as Snape dies and we get celebrate who cares how!
Yes, there is another theory below it that involves Dobbie and Twinkie marrying.

Snape ends up escaping to New Orleans, where he makes his fortune with a line of notoriously potent daiquiris. And marries Marie Levaux.

Harry wakes up and Ron is in the shower. It was all a dream!

Petunia hearts James Potter. That's why she hates Harry so much!
No, no, she loves Sirius Black!
No she is Voldie's long-term mistress!
No, McGonagall is Voldie's mistress. :)
(This is why I heart fans.)
