For cryin' out loud, people, she told a joke about farm animals and her husband's ineptitude in dealing with them. It's a joke that has been around for eons. It's not like she used a strong of four letter words, or dressed in a skimpy little pop dive outfit and mounted the horse on stage. She did what every other normal housewife in the country does... poked fun at her husband. This whole reaction has to explain why when I go camping now, I have a hard time finding sticks for kindling. If those sticks are located where they seem to be these days, you can keep them. I certainly don't want them back, and your proctologist would charge double to remove them anyway.
Look, I'm sorry but I find that kind of scatalogical humor disgusting, I certainly don't want to hear about strippers and equine masturbators from the first lady.
