Smooth As A Baby's Non-Existent Bottom

TV is advertising an "Infinity Razor", claiming it will never get dull.

If you happen to be among the last alive at the final moment of existence, test that shaver out. It may be the finite end of everything, but at least you can greet the void without stubble or irritating razor burn.

If the TV claim is true, as they often are, the last thought of humanity might be along the lines of "wow...still sharp."
