Lefties do so love some skins on the wall. Without a doubt, the most consistently clueless individuals I knew in college were the elementary education majors.
Ditto, with the exception of my pastor's daughter who is brilliant and just wants to work with kids, and one guy who I took a speech class with who was goofy, but I can just see him being the best darn math teacher ever.
When people talk about how great teachers are, it's because the really good ones stand out in your mind as life-changers who are cherished forever. In my case, I can remember one horror story for every fond memory. Of course, I was a pretty unhappy child, so take it with a grain of salt.
