I was thinking back to my PGCE course and it really was dreadful. I remember one of our tutors solemnly telling us that if the job was getting too much and you found yourself become stressed and anxious - leave teaching for the sake of the kids. 
Also another tutor showing us how we could draw little pictures to try and convey important messages to parents of EAL kids. I could see where she was coming from but I remember us all cracking up imagining some hideous Pictionary situation. (This was part of dire module we HAD to take called Embracing Diversity.)
I'm sure there were more - anyone else?
