I found a video on YouTube called "Basic Typing Methods". It was produced by the Navy in 1943 as a brief lesson in basic typing (hence the title).

Here are my reasons: 1) I don't think the woman smiles. Ever. Even though she's won global awards for her typing, apparently. 2) Any short produced by the military in the 1940's could use a good riffing. 3) Nobody does a better job of riffing shorts than you guys.
