Pop: Okay, you got the dog you wanted, so now I get to have the Hayabusa I want.
Mom (who isn't the world's fasted thinker) [PAUSE, then] No, you bought that Ford van you wanted, I got the dog, and now we're even, so if you get the Hayabusa, I get a horse, and your van can tow the horse trailer!
Pop: The Hayabusa will fit in the van. It won't need a trailer.
Mom (silent but unconvinced)
Note: This debate has no end in sight.
