A while back, I went to a friend's house, and his daughter's convertible was in the driveway with the top down.
A couple hours later, I went back outside, and the top was up, and she and her boyfriend were in the car with the top up.
Without even thinking, and being the smartass I am, I blurted out and yelled across the yard "What are ya doin, HOTBOXING in there ?!?!?!"
Next thing there is a bunch of giggling inside, and the door opens, and a big cloud of smoke comes wafting out.
