funny joke, do you get it.?

there was a man (his name was bob) and a wife (her name was maci) were fighting because bob forgot maci's birthday present." First thing tomorrow I want to go out the door and said I want to see something that go's from 0 to 200 in 3 seconds in that driveway." Maci yelled at Bob

So the next morning bob was out the door earlier than usual, So Maci woke up,went out side to see a small box sitting in the middle of the driveway she. She got it,brought it in, and opend it.

It was a scale
