Halo's developers have frequently hidden small easter eggs and in-jokes in places that are difficult to access or see, including in very small print on weapons themselves. For example: the hippo in Halo printed on shotgun cartridges, or the SPNKR designation of the rocket launcher.

Halo 4 features another such witticism, this one visible on large TVs when you zoom in on the Spartan Laser heavy weapon. Here we see that the thing's real name is "Big Scary Laser," and that it carries a warning: "Do not look into beam with remaining eye." Hah, like we'd repeat that mistake!
