Most of you would probably answer: Comic Sans. A fair guess, given the sheer amount of CS-hating that exists online. (See here, here, here and here. And that's just on The Huffington Post alone.) A smaller segment would probably shriek, "Papyrus!", that 1982 creation that tries to mimic calligraphy but fails miserably.
Alas, you'd all be wrong. Because, thanks to a cheeky designers at Barth and Co., there is a Frankenstein font that puts all other typographical disasters to shame. That font is Comic Papyrus.
