Britney Spears says that the thing she finds funniest is "when people trip or fall or run into something".
She told Harper's Bazaar that she doesn't want to be mean, but "I can't help it. If they really hurt themselves, then I feel bad, but if they accidentally do it and they stand up and act cool like nobody saw them, I have to laugh".
Maybe Britney really is just like us, after all. Maybe her heart is just cold and dark.
