Lego's Time Cruiser collection is a strange collection of sci-fi machines that might occupy this list all by itself. Still, this has to be the weirdest set of the whole series. It's supposed to look like some kind of in-car time machine, but the market has been cornered by Dr. Brown and his time-traveling delorean. It looks like something from the Batman comics that the Joker travels through time, and new lego players will no doubt be completely baffled by the design. What the hell is that propeller for? If time machines ever became a reality, we can be sure they wouldn't look like this.
