I went down to the parking garage to see the car I had won. It was green and looked like a car. But I started wondering if they had really intended for me to win the car this way. For one thing, if I just drove it away, I wouldn't have any papers to prove that I owned the car! At the very least, I should check with someone about this, and make sure I had understood the situation correctly, and if I had, they could hook me up with the papers.
So I went back in, and they had gathered everybody around for a crisis meeting: It seems someone had stolen the keys to the car, which were supposed to be the grand prize at the thing after the dinner!
I wanted to return the keys, but didn't want to admit that I had been greedy and thought I deserved them for bouncing a ball into a bowl. So I spoke up with a lie, and I said "I accidentally picked up those keys! I saw them on the table and thought I had left my car keys on the table, sorry about that, here it is." Nobody believed me, though, and they booed at me.
