We only live once, but once is enough if we do it right. Live your life with class, dignity, and style so that an exclamation, rather than a question mark signifies it! Gary Ryan Blair
I used to enjoy using dots where they would be least expected, not at the end of a sentence but in the middle, creating the effect... of a skipped beat. It seemed to me the mind reacted - first!... in dots, dashes, and exclamation points, then rationalized, drew up a brief, with periods. Tom Wolfe
It's always nice to end your sentences with an exclamation mark, and not a comma. Joey Santiago
