Video: Nerf Screamers were the coolest. They had little plastic whistles embedded in them, so that they would produce a screeching noise as they flew. (As I'm typing this, I realise how patient my neighbours must have been to listen to a tiny shrieking football at all hours of the day. Thanks Karen and Paul!) Regardless, someone took the 1991 commercial advertising the Screamer's existence and replaced its trademark noise with human screams. Don't ask why. Replacing loud things -- like trains -- with human screams is just inherently funny. There really isn't another side to this. If you're not laughing there may not be hope for you in this world.
