Input: Text: so i was 3 when this happened.  it was halloween and my friend and i were going to dress as batman and robin.  i was batman and he was robin.  now since we were little kids we wanted to be in our costumes all day and play pretend, so we did just that.  we ran around his house climbing up furniture and jumping and doing somersaults. at the time we felt unstoppable.  now my friend had bunked beds which meant a taller object to climb and jump off of.  but wait, we were dressed as batman and robin.... we were superheroes. we weren't about to jump off the bunked beds.  we were going to fly off the bunked beds.  we both climb to the top and jump one at a time.  he lands perfectly, so it was my turn.  i extend my cape and i leapt for the heavens.  i landed on my forearms ultimately breaking both of my arms.
