Alaska Pipeline "Pig"
Was used for cleaning the oil pipelines. Really!! Here's some info I found:
There are two different styles of pigs that venture down the pipeline. The first pig down the line cleans it out, while the second, "the smart pig," goes through to collect the necessary data. Sending a pig down a pipeline may sound like a strange thing, but it makes the pipeline safer and more efficient.
Smart pig??? Hmmm. Not sure which one this is.
