A pig for James Bond

Do you remember when in The World is Not Enough James Bond together with a cute nerd Christmas are travelling inside the pipeline in a sort of a shuttle? In real life, the device exists under the name of pig, which has nothing to do with a domestic animal, but stands for Pipeline Inspection Gauge. I learned the term last week and find it amusing. First, because it sounds funny. Second, because the devise is aptly named: originally, the pig was used to collect dirt from the inside of the pipeline, and real pigs are traditionally considered as not particularly hygienic animals. (Although it is not quite true, say zoologists.) And third, because even such an insipidly named movie you can serve as a source of useful terms. I should go and see Goldfinger or Octopussy immediately!
