I did a ton of stupid shit as a little kid.
First time skiing, I insisted that i already knew how to ski and didn't need their help. They let me try to ski my way down a bunny hill, so, being the pro I am,  I gain as much speed as a little 5 year old is capable of, and proceed to trip over some snow and tumble headfirst down a generally flat hill.
Another time I had to piss really bad, so I stopped in some glades, pulled down my pants and began to drain the main vein. Some snowboarders came out of nowhere, so I quickly zipped up my pants, and finished what was left in my pants. I decided I wasn't going to embarrass myself, so I skied around the whole day in very uncomfortably wet snowpants.
