What's the stupidest thing you've done in your life ?

Few years ago I joined a contest only few days before it, where you were supposed to cover as much distance as possible by hitchhiking or walking only in a team of 2 on a single week-end. The starting and ending point were the same. We did over 2700km, went to Berlin, spent less than 1hr and a Kebab there before starting to race back.

Why was it stupid ? 2hr of sleep from Friday to Monday morning, we almost got late (we came back less than 30 minutes before the time runs out), walked for 7 hours in the middle of nowhere during the first night. And we had a final Monday afternoon :hypers2:

But we won.

What about you ?
