Paychecks:

People like to say that they want a paycheck with "lots of zeroes in it." Seems to me that they really should prefer a paycheck with "lots of nines in it." Replacing any zero with a nine would be an often substantial improvement, unless it's one of those unfortunate negative paychecks. What's more, asking for nines avoids the embarrassment of leading zeroes ("we'll pay you $000,005").

There's still the problem of digits after the decimal point; an employer can easily and cheaply pay you a paycheck with an infinite number of nines (or, to save toner, pay you a paycheck that is worth the same as a number with an infinite number of nines). So next time you're looking for a job, tell the employer "I'd like a paycheck with lots of nines in it -- before the decimal point."
