Hilarious Shenanigans to Avoid Doing (especially if you're drunk)

So, you're hanging out with your best buddies, possibly imbibing some of those bad-judgement-call-inducing beverages we've all heard tales about, and after a few you realize that you want to do something wild and crazy--something hilarious, something where you can all look back on your lives and say "hey, remember that time we did that wild crazy thing? was that not hilarious? we were so very cool back then."

But, as has already been pointed out, depending on what you've been consuming, your ability to make rational decisions may not be the best. Now everyone who has been in this type of situation should have some sort of fail safe rule-of-thumb to ensure that they don't get carried away in their shenanigans. Some possible rules I've heard of are: Will I be too embarrassed to show my face at work tomorrow if I do this (if so, do not proceed)? Will there be photos of this that I will be embarrassed for my grandmother to see and since we are Facebook friends, she most definitely will (if so, do not proceed)? Will I go to jail (if so, do not proceed)?
