Joerg really has that evil genius act down pat - especially the laugh, but his YouTube channel could be just as effectively titled the "You'll Shoot Your Eye Out" Channel. I think he even pretended to do that once, a year or two ago.
This phrase always makes me think of a dual-use eating utensil. Like a spork, but with a pencil at one end - so you could jot down notes while eating SpaghettiOs. This would be much faster than writing them using individual letters from alphabet soup or Alpha-Bits cereal. If there were a dip pen or brush at the other end of the spork however you could make your notes using the tomato sauce from the SpaghettiOs as ink.
Apparently in 1830 or so "writing utensil" was briefly the preferred generic expression for tools used for writing, before "writing implement" and "writing instrument" won out in later years. That comparison is based on limited sources however.
