This is a question that's been dominating conversation with my friends for some time. You can have one of the following things:
- Time-travelling DeLorean with the Mr. Fusion and hover conversion
- Bernard's Watch, exactly as it is demonstrated in the CITV show of the same name. Basically, this gold watch allows Bernard to stop time.
I won't do a poll because I'm more interested in the logic behind the choice, rather than the choice itself.
