What's the worse experience you ever had in real life?

[Jacob__mybb_import1]

I'm kind of clumsy and hurt myself in weird ways all the time... here's a few:

1. In kindergarten I tripped and hit my face on the metal foot of a desk. The impact knocked my two front teeth into my head and I had to get them pulled out... I didn't have front teeth for my 1st-3rd grade class pictures.
   
2. 4th grade: Was playing on the "big toy" in our school playground, fell and landed on my nose. My face was covered in blood and my nose is still a little messed up.
   
3. 11th grade: Was trying to get to class on time after our principal stupidly shortened the class change time to 4 minutes. I tripped and fell in a dirt/gravel area and got a large scrape on my arm. Went to the nurse and got a bandage, then went on with the day... then at 10 PM I realized that there was a large cut there (apparently I landed on a rock) and had to go to the ER, wait 3 hours and get stitches.
   
4. Last fall: I was playing HvZ and got tackled by 3 zombies at the same time. I slammed into the concrete and got another cut in the same place as I did 2 years ago... I was worried that I had dislocated/broken something, and somebody called an ambulance because it looked so painful. The scar looks awesome though.
   

The worst part for me isn't the pain itself, but laying on the ground and wondering if I'm going to die, or have to spend weeks in the hospital and get a huge bill.
