Too Hot! is a paper note which was cut from the final version of the Fallout: New Vegas add-on Dead Money.
One of the cooks noticed their knife was glowing the other day. They'd left it on the stove top, and the metal started glowing red - and it didn't cool down! What kind of "Space Age" metal is this Cosmic Knife made of? It kept glowing hot for several hours, and then the knife was so weak that when we tried to use it, it simply snapped. Guess that's why the metal's not used in rockets!
