LOL! Let's see...
In high school, I raised my hand in class one day and called my History teacher Ms. (boyfriend's name)! - My current bf's name rhymed with the teacher's last name and I don't know what I was thinking! Well, my ex was in the class and I never heard the end of it for several months!
One day in middle school, the school bus was PACKED and while getting on the bus, I felt something tugging the back of my head. I thought someone was pulling my hair (I had long hair back then). I tried to turn around, but I couldn't! I realized my hair had gotten caught in the little school bus fan!!! LOL! I was like, oh crap!

So I pulled my hair out of there because it was preventing the little fan from turning...lol...I was so glad that my hair wasn't torn up, but a lot of the kids laughed at me! LOL!
I have some others, but can't remember them off hand
