Did an Easter egg on Gears 2 where on the level you start off on Dizzy's rig, if you shoot three hidden hats on insane mode everyone on the rig gets a Dizzy hat. Later in the level, when the Locust hijack a rig, and you break the glass protecting the driver the Locust driver has a hat. When you knock them off the bridge his hat flies up in the air after the explosion. Then sometime after that when the Corpser appears, he's wearing a giant Dizzy hat and shouts "YEEEHAAW!"
