The writer who neglects punctuation, or mispunctuates, is liable to be misunderstood for the want of merely a comma, it often occurs that an axiom appears a paradox, or that a sarcasm is converted into a sermonoid. – Edgar Allan Poe

There’s the Oxford comma, but I like the Shatner comma. It’s when you pepper them in, so, you know where, to add, dramatic pauses. – Nicole Leigh Shaw

A semicomma, we should note, doesn’t exist; we just made the word up. But it sounds like a punctuation mark that should exist, doesn’t it? – Richard Lederer and John Shore, Comma Sense: A Fun-damental Guide to Punctuation

The rules of punctuation seem arbitrary. How can they not, when an apostrophe looks like nothing in this world so much as a comma that can’t keep its feet on the ground? Or when, by simply placing next to that wafting comma its twin, one creates (of all things) a quotation mark? – Richard Lederer and John Shore, Comma Sense: A Fun-damental Guide to Punctuation
