Behold, the video for GEA Farm Technologies' ClassicPro silicone teat-cup liners.
A teat-cup liner, for those of you who don't know, is the bit that goes into the machine that attaches to a cow or other dairy animal's teats to form a better seal and to make the milking process more "soothing." Why it should be doing a disco dance is beyond me. But if we start asking such questions, we have to also ask ourselves why pigs seem to enjoy basting themselves in barbecue advertising, why Charlie is in a tuna commercial, what a mean-spirited cheetah has to do with Cheetos and what kind of drugs are being ingested by the folks who make Skittles commercials.
If you can find something stranger -- and it's clean and safe for work -- do let us know.
