Much has been said about the need for a "sarcasm font". What does a font tell you about the tone of what's written in it, or the personality that chose it? Here's a pictorial guide.
Copperplate: (note - copperplate is the font on my personal card.)
Harlow Solid Italic:
Papyrus: (my company used to have a safety poster about forklifts written in this font. really.)
Do you have any to add?
