A friend drank a large quantity of my nice tequila several years ago. Sooo I excercised my, "dont get mad, get even" motto. Once he had finished launching his guts all over the front yard and passed out in his westy van, we put the thing in neutral and rolled it around the neighborhood until we found a suitable place. We made sure to leave the side door open, just as he had left it. We also took his keys back to the house the party was at, so he couldn't drive drunk, if he miraculously woke up. Unfortunately I had to leave before he awoke, but I hear he was none too happy.
Ben, perhaps something similar happened to you?
