Well there's two that jump right out of my head.

The first being when I was young, like 8 at one of those "all you can eat Buffett's." I remember being super careless and trying to grab something from one of the containers, but my other hand (the one with the plate) touching the silver tray in the bar. Of course, those are super hot to keep everything warm. My reaction? To jerk my arm back and literally throw the plate across the room screaming "HOT!" Don't really remember what happened after, but I think that may be for the better xD. Oh and yeah the plate was filled with food. Spaghetti, chicken, macaroni, pizza and potatoes if I remember right.

The second being back in high school. Some reason that day I felt great....until I got to school. Suddenly while talking with my friend I got really exhausted. On a cool day I started getting really hot and sweaty. Suddenly I couldn't take it anymore I just had to try and get to the bathroom to wash my face or something, but as soon as I got up and walked a bit. My vision faded (you know like when you get up too fast and blood rushes). It faded more than usual (to the point it looked like I blacked out). Soon I regained it after holding onto something. Right after I walk it off I tried to make it there again. A few more steps is all I remember because I really did faint/black out after that. I just remember waking up moments later surrounded by a lot of others with them on the intercom calling for the nurse. Me trying to get up confused as to what just happened. Funny part about that embarrassment? Right after that I felt way better. I was only out for a few seconds if that too. Still I left for the day after that.
