Scott Adams recounts having his 4 ounce bottle of shampoo confiscated at the airport because it exceeded the maximum 3 ounce allowance, even though the sign at the airport said it could be 4 ounces and there was only about an ounce left in the bottle anyway. The money quote:

Discretion is, they say, the better part of valor.
