A millimetre is a unit of length. When Brian discovered that one who received faulty goods and complained would receive free gifts, he phoned a customer complaints line, making the rather pathetic complaint that he measured every single slice of their loaf of bread and four out of the thirty slices were two millimetres thinner than the others, and one of the slices had a hole in it (which was made by himself). (Hot Gossip)

Behind the scenesEdit

Obviously, in the real world, a millimetre is one thousandth of a metre. My Parents Are Aliens never explicitly makes this connection.

Wikipedia has a more detailed and comprehensive article on Millimetre
