If you use Comic Sans, now is the time to never use Comic Sans again. The joke of the font world, Comic Sans is silly, stupid, and makes you look completely unprofessional. This embarrassing typeface is what people thought looked cool when the Internet first came into being. They were wrong. Today there is a whole online movement to get rid of the typeface Ban Comic Sans (and they have T-shirts!). Then again, maybe we're all a little too harsh on Comic Sans.
