Re:CTRL-H Defined

Right, but the "joke" originates from actual incidents of old terminal programs storing the ^H rather than erasing the previous character. Occasionally, BBSes would have backspace set to something other than ^H. When someone would post a message, and they sent the ^H sig, their own terminals echoed a backspace, but the remote BBS simply logged the ^H as part of their post.

It's an airsoft gun. The bb's are 6mm plastic. Much less inertia and penetration capability. Not that he doesn't still need a mask, but they're not as powerful as your run-of-the-mill 4.5mm steel bb's.
