 After a couple of minutes of typical movie credits, we are treated with a  final, classic Guide entry. It refers to Arthur Dent carelessly speaking  words about a towel, which ends up being interpreted by a pair of warring  factions as a devastating insult. They then spend thousands of years coming  to Earth bent on revenge, however "due to a terrible miscalculation of  scale the entire battle fleet was accidentally swallowed by a small dog".  The Guide concludes with the reassuring nugget of wisdom, "this sort of  thing is going on all the time".
