The origins of Comic Sans date back to October 1994, when Microsoft designer Vincent Connare set out to create a font inspired by the lettering style found in The Dark Knight Returns and Watchmen. Though initially meant to replace the Times New Roman used in Microsoft Bob's speech bubbles, the font wasn't finished in time and instead made its premiere in 3D Movie Maker. Its rise to infamy, however, didn't truly begin until August 24th, 1995: the day Windows 95 launched with Comic Sans in tow.
This is how Connare described its legacy to The Wall Street Journal in 2009: "If you love it, you don't know much about typography... if you hate it, you really don't know much about typography, either, and you should get another hobby."
And here's Comic Sans Café, an actual website that still exists on Microsoft's servers.
With that in mind, let's enjoy the Sincerity Machine for what it is, a Comic Sans typewriter made by Jesse England. (The name is inspired by Dorothy Gambrell's "Cat and Girl" comics.)
