If there is one thing that we learned at the Natural History museum today, it is this... Never look over your shoulder. Even if you feel hot breath on the back of your neck. Because if you turn around, the only thing you will see is a window to the past. A past that you don't want to revisit. A place where humans grow horns...
And huge, teeth-like things that they use to stab other things...
And then, if you look hard enough through that window... past the horns, and the teeth... you will see something frightening. We're talking... the kind of fright that finds its way into your nightmares... clowns.
Blow up those balloons people. The parade is coming.
