I typed in "Cow Udder" in Alta Vista's search engine, and....well.....just click the link to find out.  I'm just warning you, I hope you didn't just eat.
Big ol' milk bag 
FWIW and JMHO, I don't believe a word about milk being bad for you.  Try drinking a gallon?  Jeeez!  Okay, drink a gallon of vinegar, or orange juice.  Same thing's gonna happen:  BARF!  All that lactic acid can't be handled all at once, anyway.
Remember, the best things in life are enjoyed in moderation.
