Mike and I have a friend from undergrad who tended to get 'inspired' while drinking. One night, while thoroughly inebriated, he announced that he was going to drive to some girl's house. Everyone told him he was far too wasted to drive and that he would likely get a DUI at the very least.
Our drunk friend stood up and gave this speech with conviction and passion:
Yes, there is a possibility that I will get a DUI. There's always that possability. But, you guys are thinking about this the wrong way. Take the cost of my possible DUI and distribute that cost over every instance I've ever driven drunk or ever will drive drunk and you'll see that the benefit of me driving drunk outweighs the cost in this instance, tonight.
Upon hearing this convoluted reasoning, we all looked at each other, nodded, tackled him, held him down, and took his keys out of his pocket.
And, yes, that drunk guy is now in law school.
And doing very well there, too.
