when your trying to go through the drivethru of taco bell and your window does not roll down so you must open the door to recieve your food. When you do this your idiot dog pops out the back seat and takes off running and your car starts rolling forward because you forgot to put it in park. Everyone behind you in line is wondering what the fuck is going on. Really happened to me, and i cracked up later thinking about it. I was really embarassed though.
