I've played through one somewhat recently for our Dawnforge game. I think it was an actual Dawnforge adventure called Path of Legend. In it, we were all first-level characters and the first thing we ended up doing was competing in a contest for the city where we were staying (spoiler alert for those who plan to play this adventure).
Okay, so we ended up getting suckered into competing in this marathon during a holiday for the city. The details are a little fuzzy, but it involved having to quaff large amounts of an alcoholic beverage, and then making a check to see if that made you drunk (a Fort save, maybe?). So, if you fail your save, you're drunk and it affects your Dex, I think. During the race, it was kind of like a skills-based race, like an obstacle course. You had to use Balance, Climb, Swim, Tumble, and a bunch of other skills (I think that there were even some logic-based skills you needed to use), and at each checkpoint you had to drink more alcohol and make more skill checks. It was really funny, a great way for the party to get to know each other, and also a fun way to almost force everyone to make random skill checks (without making them seem random).
We had a blast with that.
