I've found much of this site humorous. More so if you have read the Harry Potter books or follow it at all. Still can be funny regardless though.

I still think Trouble at Hogwarts was the best. The secret in there makes me laugh every time. When Voldemort attacks Snape pause it and skip frames till you see a star. Then click it for a funny scene.
