Have you ever had a teacher who you absolutely could not stand?

I finished a technology "discovery" class a few months ago and looking back at it, it was such crap. I was proofreading a report for my guy friend (who's a senior) while I was on the computer in that class and he's like "Who's report is this, your name isn't Jerome?" But then he called the English 12 teacher and was like "I believe one of my students is doing any assignment for your class blah blah blah." And so I had to explain that I was only proofreading it. I had that English 12 teacher for AP English too. She excused me but the technology teacher sent a report to the office anyways. ******* ****. I'm mad right now thinking about it because I just got report cards in the mail and I failed that technology class. Ugh. Anyone want to share their stories?
