It's "fewer" when talking about quantities of distinct units, such as people, bricks of Soylent Green, and wizards who turn you into a whale, and it's "less" when talking about more indistinct amounts, such as water, time, and hatred. Rule of thumb: if it's plural, use "fewer"; if it's singular, use "less." I hope T-Rex and I have both taught you a lessen. ~_^...and the punster, as well, it appears.
