Whats the most embarrassing thing you ever did?

ok I did this when I was about 4 years old but it still haunts me to this day...
I went to a local sports camp for the summer and for the end of summer party we had a cookout and a swimming party at our local park. After we had our picnic they had 2 tents set up for us to change into our swimming clothes, so I changed my clothes in there and went swimming. Well after swimming, our parents came to pick us up, so instead of letting us change in the bath house which was crowded, they took us up to the top of the hill (sopping wet) to wait for our parents. Well, I was always brought up to change your clothes after you get out of the pool, like it was a big no-no to my mom to walk around in wet clothes. So I walked behind a tree....and stripped naked and began to change my clothes. I hear laughter and turn around to see all the "big" kids standing behind me and laughing. The head counselor came over and tried to cover me up and he was stifling laughter the whole time....
I didn't think anything of it until the next day when all the older kids kept asking "why were you naked yesterday?"
and I just kept telling them I was "pretending there was a tent"
I didn't think it was a big deal until I got older and I realized how funny I must have looked standing there butt naked in the middle of a park changing clothes....
