Meet the Robinsons2007

Carl:
What do you mean, don't go to the family? How can we not go to the family in this time of family crisis? By leaving the garage door unlocked, you let the time machine get stolen, and now the entire time stream could be altered! That and someone took my bike.

Wilbur:
Look, I told you. It's gonna all work out. First, we keep Lewis in the garage away from everybody. I show up and give him the pep talk of the century. Then he fixes the time machine.

Carl:
Why is it an acorn?

Wilbur:
I didn't have time to sculpt everything. Okay, now, the time machine is fixed. His confidence in inventing is restored. He goes back to the science fair, fixes his Memory Scanner, thus restoring the space-time continuum.

Carl:
What about taking him back to see his mom?

Wilbur:
I just told him that to buy some time.

Carl:
Oh, yeah, can't see that one blowing up in your face.

Wilbur:
Trust me. I got it under control. Wilbur Robinson never fails. But on the slight chance that I do...

Carl:
"On the slight chance," yeah. You know what? I'll run the numbers.

Wilbur:
What is it?

Carl:
Well, it's not. It doesn't pertain to anything in. You know, there's not necessarily, there's a 99.999999% chance that you won't exist.

Wilbur:
What?

Carl:
And I didn't want to tell you, but I did.

Wilbur:
I won't exist?

Carl:
And where does that leave me? Alone, rusting in a corner.

Wilbur:
What am I worried about? Now, blueprints?

Carl:
If this thing ever blows over, I really gotta get away from you and get some quiet time.
