Because babies can screw up history, too.
Are you a time-travel fan with scads of free time, and in possession of a baby? Well then, assuming you didn't steal that baby in an effort to destroy/save/fight the future, we hope you'll draw inspiration from this family.
That's right -- it's a DeLorean stroller. The coolest thing about this DIY time machine is that it looks like it was made almost entirely from cardboard. So not only is it awesome -- it's probably pretty cheap to build, too. So if you can trip, hit your head on the toilet, and unleash the Doc Brown from within, you might consider building one yourself.
