I associate Helvetica with a certain sense of order — refinement, that with overuse, becomes lazy shorthand for being thoughtful. It’s a tasteful business suit, but it’s still a business suit. Comic Sans, on the other hand, just makes me think of clowns.
Comic Helvetic, an experimental font from designer Alexander Pravdin, is the “wearing a business suit with clown shoes” of fonts (via kottke.org).
