Mean stuff can be funny

I just think it's funny that there's a t-shirt out there that, in reference to the Harry Potter series, says "-someone- dies on page 596. There, I just saved you 4 hours and $30." (I substituted the "-someone-" because I'm not quite mean enough to blow that surprise here; just mean enough to laugh at it.) I think it's funnier that the company selling the shirt, in its description of the shirt, basically says "At least we didn't tell you it was -so and so- Oh yeah... *Warning: Harry Potter Spoiler Alert*"
