What was the most stupid thin you have ever done, heard, said, or seen? mine was when I was jumping off the to step of my bed,(loft bed) I made a 10 point landing on a gun rest. Needless to say, I twisted my ankle.
The first thing that pops to my mind when you mention 'Stupid Things' is the time when i was playing a game called 'Tag' which is also known as 'It' on a roof. I was running and then fell straight through it onto a car. I didn't get hurt but it was stupid...
